2 x 2 x 13 = 52
2 x 17 = 34
Prime factorization of 75 = 3 x 5 x 5
2 x 2 x 17
2 x 3 x 5 = 30
No.
It is: 2*2*2*2*3*3*7 = 1008
prime factorization of 32: 2 x 2 x 2 x 2 x 2
The prime factorization of 52 is: 2 x 2 x 13
52 is composite. You need at least two numbers to find a GCF.
The prime factors of 25 are 5 x 5 (or 52).
