The GCF is: 165
16.5*2=33
1,2,3,4,5,6,10,11,12,15,20,22,30,33,44,55,60,66,110,132,165,220,330,660 1,3,5,7,11,15,21,33,35,55,77,105,165,231,385,1155 Common set: 1,3,5,11,33,55,165
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
Since 220 is a factor of 660, it is automatically the GCF.
The GCF is: 165
The greatest common factor of 315 and 660 is 15.
The Greatest Common Factor (GCF) is: 60
The GCF is 60.
The GCF is: 3
The GCF is 11.
The least common factor of 12,15, and 22 is one, because it has no other common factors.
