#3#

Explanation:

The only factors of #3# are #3# and #1#. We know the GCF will not be greater than #3#, and #3# is a factor of #120#, so this is our GCF.

Normally, we would list the factors of the numbers and highlight the ones in common, but since #3# has only 2 factors, we were able to cut to the chase.
