A prime number can only be divided by one or itself. Non prime whole numbers can be written as a product of their prime factors. We can help you find prime numbers for any number you can think of.

Just type in a number to find its prime factors.

By factorization of Your chosen integer we follow 5 simple steps:

- 1. We write Your number above a 2-column table
- 2. We divide the number by the smallest possible prime factor
- 3. We write down on the left side of the table the prime factor and next number to factorize on the ride side
- 4. We continue to factor in this fashion (we deal with odd numbers by trying small prime factors)
- 5. We continue until we reach 1 on the ride side of the table
