# Quick Answer: What Are The Six Factors Of 18?

## What is the factor of 10?

The factors of 10 are 1, 2, 5, and 10.

You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third.

2 x 5 = 10, so 2 and 5 are factors of 10.

1 x 10 = 10, so 1 and 10 are also factors of 10..
