The 6 factors of 10 and 30?

Answer 1

I am guessing you want common factors. That is to say factors common to 10 and 30

The common factors would be:

1,2, 5, and 10, but there only 4 that are common.

15 and 30 are factors of 30 so if you add those you have 6 factors.

Answer 2

1, 2, 5, 10

1, 2, 4, 5, 10, 20

1, 2, 3, 5, 6, 10, 15, 30
