What is the greatest common factor of 8x and 40?

For this case we have that by definition, the Greatest Common Factor or GFC, of two or more integers is the largest integer that divides them without leaving a residue.

So:

We look for the factors of both numbers:

8: 1, 2, 4, 8

40: 1, 2, 4, 5, 8, 10, 20

It is observed that 8 is common.

So, the GFC of 8x and 40 is 8

8
