To determine the greatest common factor, express each number in terms of its prime factors.
99 = 3 x 3 x 11.
165 = 3 x 5 x 11.
The factors common to both numbers are 3 and 11.
The greatest common factor is therefore 3 x 11 = 33.
The greatest common factor of the numbers 165 and 6 is 3.
The Greatest Common Factor of 99, 132, 165: 33
The Greatest Common Factor of 165, 48, 60: 3
The Greatest Common Factor (GCF) is: 15
The GCF of 75 and 165 is 15
The greatest common factor of 30 and 165 is 15.
The GCF of 64 and 165 is 1.
It is: 3
