The answer is 3. Factor out each term to get: 39 = 3 x 13 87 = 3 x 29 The GCF is 3 since that term is common for these terms. In other words, 39 and 87 have the common factor of 3.

Factor out each term to get: 20 = 2² x 5 99 = 3 x 33 = 3² x 11 Since these terms don't have the common factor, the common factor is 1.
