Factorization of the Integer number is a mathematical procedure
of extracting all of its Prime divisors, also called Factors. This procedure is
also known as Factoring or Factorisation. Any Integer number could be presented
as a Product of its Factors.

Prime Numbers, or simply Primes have only two trivial divisors:
1 and the number itself. Any Integers except for Primes are called Composite
Numbers; they contains at least three divisors. Sample Factorization:
12 = 2 * 2 * 3, where 2 and 3 are Primes
To Factorize the Integer using online Calculator
enter the it into the text box and click on the "=" screen button. You will
see the number presented as product of the Primes. Number 1 as a trivial
divisor is not included in the list.

Primality test (in other words, check if the Integer
number is Prime) could be performed in the same way as Factoring:
enter the number and calculate Factor(s): if the list contains only one Factor,
then the number is Prime and vice versa.

For faster computation, Primality check could be performed without Factoring.
Enter the Number and click on the button "IsPrime" located at the top
to find the answer fast.
