The GCF of 14, 31, 39, and 56 is 1. One way to solve the problem is to notice that 31 is prime, and can't possibly be a factor of 14, which is smaller.

If you prefer, you can write the prime factorization of each number in the set and find the GCF:
The prime factorization of 14 is 2*7
The prime factorization of 31 is 31 (1*31)
The prime factorization of 39 is 3*39
The prime factorization of 56 is 2*2*2*7
So the GCF is 1.
