Hi there!
The greatest common factor is : The greatest factor that divides two numbers.
The two numbers could be : 28 and 24.
Step-by-step 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! :)
