The GCF is: 165
The GCF is: 165
Ascertain the prime factors of both numbers :- 660 = 2 x 2 x 3 x 5 x 11 1155 = 3 x 5 x 7 x 11 The only factors (other than 1) that both numbers have in common are 3, 5 and 11. The greatest common factor is therefore 3 x 5 x 11 = 165 165 is the GCF of 660 and 1155
It is: 165
The GCF is 60.
16.5*2=33
Since 12 is a factor of 660, it is automatically the GCF.

The GCF is 60.
The greatest common factor of 315 and 660 is 15.
165, 330, 495, 660, 825, 990, 1155, 1320, 1485, 1650.
Since 220 is a factor of 660, it is automatically the GCF.
