To find the greatest common factor of two numbers you first need to express those numbers as prime factors:
34 = 17x2
68 = 17x2x2
The next step is to identify any common prime factors. In this case, both numbers have 17 and 2 as prime factors. Thus to find the GCF, we multiply these numbers together:
17x2 = 34.
Thus the greatest common factor of 34 and 68 is 34.
The Greatest Common Factor (GCF) is: 34
The greatest common factor of 34 and 48 is 2.
The greatest common factor of 25 and 34 is one.
The greatest common factor of 16 and 34 is 2.
The greatest common factor of 12 and 34 is 2.
The Greatest Common Factor of 51 and 34 is 17.
The greatest common factor of 34 and 98 is 2.
The Greatest Common Factor of 34 and 66 is 2.
The greatest common factor of 34 , 17 = 17
The GCF is 1.
The Greatest Common Factor of 34, 51, 169 is 1.
The greatest common factor of 34 and 76 is 2.
