The GCF of 72, 90, and 120 is: 6
To find the greatest common factor of two numbers we first need to split them into their prime factors: 102 = 2x3x17 120 = 2x2x2x3x5 The next step is to identify the common factors. In this case both numbers have a 2 and a 3 as prime factors. To find the GCF we multiply these common factors together: 2x3 = 6 Thus 6 is the greatest common factor of 102 and 120.
the greatest common factor is 6
The greatest common factor of 3 and 1,200 is 3.
The greatest common factor of 42 and 66 is 6.6
