## What are all the numbers that go into 27?

27 = 1 **x** 27, or 3 **x** 9. Factors of 27: 1, 3, 9, 27.

## Which are the factors?

**Factor**, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are **factors** of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The prime **factors** of a number or an algebraic expression are those **factors** which are prime.
