Frequently asked questions
What is a factor?
A factor (or divisor) of a number is a whole number that divides it exactly, with no remainder.
How many factors does a prime number have?
Exactly two — 1 and the number itself. Any number with more than two factors is not prime.
How is this different from prime factorization?
This lists all factors (like 1, 2, 3, 4, 6, 12 for the number 12); the Prime Factorization Calculator instead breaks a number down into its prime building blocks (12 = 2² × 3).
