2 x 2 x 17 is the prime factorization of 68. You need at least two numbers to find a GCF.
The GCF of 2, 2 and 17 is 1.
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.
