The greatest common factor of 45 and 120 is 15 .

Hint: any number that ends in 0 or 5 has five for a factor.

So, obviously, 5 is a common of 45 and 120.

To see if 5 i s the greatest common factor, divide both of these numbers by 5 and see

what you have left. Do these remaining numbers have any common factors?

The GCF is 15.
