Answer:

The GCF is going to be 7

Explanation:

This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here

The prime factorization of 21, 3 × 7 = 21

The prime factorization of 28, 2 × 2 × 7 = 28

The one and THE only common factor is 7, which is going to be the GCF
