Frequently Asked Questions

Factors of a number are all positive integers that divide it without a remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12.

Factors include all divisors of a number. Prime factors are only the prime numbers among those divisors. The prime factors of 12 are 2 and 3, since 12 = 2 x 2 x 3.

Test each integer from 1 up to the square root of the number. If it divides evenly, both the divisor and the quotient are factors. This method avoids testing every number up to the full value.
