What are the common factors and greatest common factor?

Answer 1

All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.

Answer 2

When you find a greatest common factor, or GCF, you find all the factors that go into a number. Lets try it with 8 and 12.

Factors of 8: 1, 8, 2, 4

Factors of 12: 1, 12, 2, 6 3, 4

The factors that were the same are the common factors. For problem, they were 1, 2, and 4. The greatest was 4. That's the GCF for that problem. Hope this helped!
