The GCF is: 165
It is: 165
Since 220 is a factor of 660, it is automatically the GCF.
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
The Greatest Common Factor (GCF) is: 60
The greatest common factor of 315 and 660 is 15.
The GCF is: 3
The GCF is 11.
The GCF is 60.

You need 2 or more numbers to perform GCF
lowest common factor of 20 and 33 is 660 mislead you there, dont think there is any greatest common factor because one number is odd and one even
