Answer 2

Hi there!

The greatest common factor is : The greatest factor that divides two numbers.

The two numbers could be : 28 and 24.

Explanation:

1 × 28 = 28                    1 × 24 = 24

2 × 14 = 28                    2 × 12 = 24

4 × 7 = 28                      3 × 8 = 24

                                      4 × 6 = 24

28 and 24 have the factors 1, 2 & 4 in common, in which 4 is the greatest common factor.

There you go! I really hope this helped, if there's anything just let me know! :)
