What is a Factor?

A factor is an integer which divides another number with no remainder. A factor is the decomposition of a number to evenly divisible parts. Factors almost always are taken for positive numbers.

For example, the number 6 has the factors 3 and 2. (It also has the number 6 and 1, as you can multiple 1*6 to equal 6).

An interesting application for factors is with prime numbers. Primes are numbers which can only be divided by '1' or themselves equally; there is no further way to reduce them. When you do prime factorization, you find all of the primes that make up a number when multiplied together – even if a prime number appears more than once.

Using the Factor Calculator

To use the factor calculator, simply enter a number into the Number to Factor box. Leave the Factor Types pull-down as All Numbers (unless you want to only see primes).

Then, hit the Factor Number button. The tool will return all factors that divide your number equally, including 1 and the number itself. If you enter a negative number or a prime, you'll only get the number back and 1.
