It is: 1
The GCF of 52 and 68 is 4
The prime factorization of 68 is 17 x 2 x 268 is composite. It is 2 x 2 x 17.
The prime factorization for 68 is: 2 x 2 x 17
Method of prime factorization is a good method to find GCF.P.F. of 68 = 2x2x17P.F. of 56 = 2x2x2x7It is clear that 2x2 is the greatest common factor.Therefore, GCF of 68 and 56 = 4.
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.
Prime factors of 68 are 22 x 17.
It is: 22*17 = 68
2 x 2 x 17 = 682 x 2 x 19 = 762 x 2 x 23 = 922 x 2 = 4, the GCF
As a product of its prime factors: 2*2*17 = 68
68 = 22 x 17
To find the greatest common factor (GCF), first find the prime factorization of the two numbers. The GCF is the product of all of the prime factors the two numbers have in common. Prime factors of 28: 2, 2, 7 Prime factors of 68: 2, 2, 17 They have in common: 2, 2. 2x2=4 The GCF is 4.
