This calculator presents:. For the first prime numbers, this calculator indicates the index of the prime number. The limit on the input number to factor is less than 10, less than 10 trillion or a maximum of 13 digits. Prime factorization or integer factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number.

This is also known as prime decomposition. We cover two methods of prime factorization: find primes by trial division, and use primes to create a prime factors tree.

Say you want to find the prime factors of using trial division. Start by testing each integer to see if and how often it divides and the subsequent quotients evenly. The resulting set of factors will be prime since, for example, when 2 is exhausted all multiples of 2 are also exhausted. List the resulting prime factors as a sequence of multiples, 2 x 2 x 5 x 5 or as factors with exponents, 2 2 x 5 2.

To find the prime factors, you start by dividing the number by the first prime number, which is 2. If there is not a remainder, meaning you can divide evenly, then 2 is a factor of the number. Continue dividing by 2 until you cannot divide evenly anymore.

Write down how many 2's you were able to divide by evenly. Now try dividing by the next prime factor, which is 3. The goal is to get to a quotient of 1. We can't divide by 2 evenly anymore.

We can't divide by 3 evenly anymore.

See also in this web page a Prime Factorization Chart with all primes from 1 to The prime factorization is the decomposition of a composite number into a product of prime factors that, if multiplied, recreate the original number.

Factors by definition are the numbers that multiply to create another number. A prime number is an integer greater than one which is divided only by one and by itself. Note the the only "prime" factors of 72 are 2 and 3 which are prime numbers.

Let's find the prime factorization of Solution 1 Start with the smallest prime number that divides into 72, in this case 2. Again we can use 2, and write the 36 as 2 x 18, to give.

Taking the left-hand numbers and the right-most number of the last row dividers an multiplying then, we have. Note that these dividers are the prime factors. They are also called the leaves of the factor tree.

The number 66 is a composite number so, it is possible to factorize it. In other words, 66 can be divided by 1, by itself and at least by 2, 3 and A composite number is a positive integer that has at least one positive divisor other than one or the number itself.

In other words, a composite number is any integer greater than one that is not a prime number. The prime factors of 66 are 2, 3 and Factor tree or prime decomposition for 66 As 66 is a composite number, we can draw its factor tree:. What is prime factorization? Definition of prime factorization The prime factorization is the decomposition of a composite number into a product of prime factors that, if multiplied, recreate the original number.

Prime factorization example 1 Let's find the prime factorization of Prime Factorization Calculator Please link to this page! Sample Number Factorizations. Prime factorization of 10 Prime factorization of Prime factorization of Prime numbers are natural numbers positive whole numbers that sometimes include 0 in certain definitions that are greater than 1, that cannot be formed by multiplying two smaller numbers.

An example of a prime number is 7, since it can only be formed by multiplying the numbers 1 and 7. Other examples include 2, 3, 5, 11, etc. Numbers that can be formed with two other natural numbers, that are greater than 1, are called composite numbers.

Examples of this include numbers like, 4, 6, 9, etc. Prime numbers are widely used in number theory due to the fundamental theorem of arithmetic.

Prime Factorization of 64 and 96

This theorem states that natural numbers greater than 1 are either prime, or can be factored as a product of prime numbers. As an example, the number 60 can be factored into a product of prime numbers as follows:. Prime factorization is the decomposition of a composite number into a product of prime numbers. There are many factoring algorithms, some more complicated than others. One method for finding the prime factors of a composite number is trial division. Trial division is one of the more basic algorithms, though it is highly tedious.

It involves testing each integer by dividing the composite number in question by the integer, and determining if, and how many times, the integer can divide the number evenly. As a simple example, below is the prime factorization of using trial division:. Since is no longer divisible by 2, test the next integers. It can however be divided by This is essentially the "brute force" method for determining the prime factors of a number, and though is a simple example, it can get far more tedious very quickly.

Another common way to conduct prime factorization is referred to as prime decomposition, and can involve the use of a factor tree. Creating a factor tree involves breaking up the composite number into factors of the composite number, until all of the numbers are prime. In the example below, the prime factors are found by dividing by a prime factor, 2, then continuing to divide the result until all factors are prime.

The example below demonstrates two ways that a factor tree can be created using the number While these methods work for smaller numbers and there are many other algorithmsthere is no known algorithm for much larger numbers, and it can take a long period of time for even machines to compute the prime factorizations of larger numbers; inscientists concluded a project using hundreds of machines to factor the digit number, RSA, and it took two years.

It is impossible to formulate precise recommendations based on those Monte- Carlo results, but many researchers follow a rule of thumb that if your sample size is 50 or more then serious biases are unlikely, and if your sample size is over 100 then you should not be concerned at all with the normality assumptions.

Outliers are atypical (by definition), infrequent observations. Because of the way in which the regression line is determined (especially the fact that it is based on minimizing not the sum of simple distances but the sum of squares of distances of data points from the line), outliers have a profound influence on the slope of the regression line and consequently on the value of the correlation coefficient. A single outlier is capable of considerably changing the slope of the regression line and, consequently, the value of the correlation, as demonstrated in the following example. Note, that as shown on that illustration, just one outlier can be entirely responsible for a high value of the correlation that otherwise (without the outlier) would be close to zero. Needless to say, one should never base important conclusions on the value of the correlation coefficient alone (i.

Note that if the sample size is relatively small, then including or excluding specific data points that are not as clearly "outliers" as the one shown in the previous example may have a profound influence on the regression line (and the correlation coefficient).

Typically, we believe that outliers represent a random error that we would like to be able to control. Unfortunately, there is no widely accepted method to remove outliers automatically (however, see the next paragraph), thus what we are left with is to identify any outliers by examining a scatterplot of each important correlation.

Needless to say, outliers may not only artificially increase the value of a correlation coefficient, but they can also decrease the value of a "legitimate" correlation. See also Confidence Ellipse. Quantitative Approach to Outliers. Some researchers use quantitative methods to exclude outliers. In some areas of research, such "cleaning" of the data is absolutely necessary.

For example, in cognitive psychology research on reaction times, even if almost all scores in an experiment are in the range of 300-700 milliseconds, just a few "distracted reactions" of 10-15 seconds will completely change the overall picture. It should also be noted that in some rare cases, the relative frequency of outliers across a number of groups or cells of a design can be subjected to analysis and provide interpretable results. For example, outliers could be indicative of the occurrence of a phenomenon that is qualitatively different than the typical pattern observed or expected in the sample, thus the relative frequency of outliers could provide evidence of a relative frequency of departure from the process or phenomenon that is typical for the majority of cases in a group.

Correlations in Non-homogeneous Groups. A lack of homogeneity in the sample from which a correlation was calculated can be another factor that biases the value of the correlation. Imagine a case where a correlation coefficient is calculated from data points which came from two different experimental groups but this fact is ignored when the correlation is calculated. Let us assume that the experimental manipulation in one of the groups increased the values of both correlated variables and thus the data from each group form a distinctive "cloud" in the scatterplot (as shown in the graph below).

In such cases, a high correlation may result that is entirely due to the arrangement of the two groups, but which does not represent the "true" relation between the two variables, which may practically be equal to 0 (as could be seen if we looked at each group separately, see the following graph). If you suspect the influence of such a phenomenon on your correlations and know how to identify such "subsets" of data, try to run the correlations separately in each subset of observations.

If you do not know how to identify the hypothetical subsets, try to examine the data with some exploratory multivariate techniques (e. Nonlinear Relations between Variables.

Another potential source of problems with the linear (Pearson r) correlation is the shape of the relation. The possibility of such non-linear relationships is another reason why examining scatterplots is a necessary step in evaluating every correlation.

What do you do if a correlation is strong but clearly nonlinear (as concluded from examining scatterplots). Unfortunately, there is no simple answer to this question, because there is no easy-to-use equivalent of Pearson r that is capable of handling nonlinear relations. If the curve is monotonous (continuously decreasing or increasing) you could try to transform one or both of the variables to remove the curvilinearity and then recalculate the correlation.

Another option available if the relation is monotonous is to try a nonparametric correlation (e. However, nonparametric correlations are generally less sensitive and sometimes this method will not produce any gains.
