Prime Factor Calculator

Prime factor calculator online

This is a handy prime factorization calculator that helps you find the prime factors of given numbers.

This prime factor calculator performs the prime factorization of one, two, three and four numbers showing results in the standard form as multiplication of the prime factors and exponential form (power form).

For two, three and four numbers the prime factorization calculator finds the GCF (greatest common factor) and LCM (Least Common Multiple) of numbers.

For prime numbers the prime factor calculator returns the number itself.

How to find the prime factors:

Just enter one, two, three or four positive integers and click "Calculate". The prime factorization calculator can handle numbers with up to 7 digits.
