This calculator will find the prime factorization of the given number. Also it will determine whether or not a number is prime. Stepbystep explanations are provided.

"Prime Factorization" is finding which prime numbers we need to multiply to get the original number.
Example:
Find the prime factorization of 60.
To find prime factorization of 60 start with the smallest prime number that divides 60, in this case 2.
60 ÷ 2 = 30
Now find smallest smallest prime number that divides 30 (again we use 2)
30 ÷ 2 = 15
15 is divisible with 3, so we have:
15 ÷ 3 = 5
5 is divisible with 5, so the prime factorization of 60 is:
2 x 2 x 3 x 5
