What is the gcf of 6 and 15?

The greatest common factor (GCF) of 6 and 15 is 3.

To find this, you can first list out the factors of each number:

6: 1, 2, 3, 6 15: 1, 3, 5, 15

Then, you can identify the greatest common factor that appears in both lists, which is 3.

Another way to find the GCF is to use prime factorization.

6 can be written as 2 x 3 15 can be written as 3 x 5

To find the GCF, you can take the common factors of both numbers, which is 3.

Therefore, the GCF of 6 and 15 is 3.
