The GCF is 3.
The GCF of 27 and 78 is 3. 27 /\ 9*3 / \ 3*3 78 / \ 39 *2 / \ 13*3 27=3*3*3 78=2*13*3 GCF=3
The GCF of 18, 27, and 78 is 3.18=2*3*327=3*3*378=2*3*13GCF=3
The GCF is 3 because for factor for 78 is 1,2,3,6,13,26,39,78 and factor for 27 is 1,3,9,27 and they both have 3 in common so the answer will be 3
