The greatest common factor of 12, 28, and 40 is 4

To find the greatest common factor of numbers, you first need to split these numbers into their prime factors:

12 = 2x2x3

28 = 2x2x7

40 = 2x2x2x2x5

You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s:

2x2=4

Thus the GCF of 12, 28 and 40 is 4.
