The GCF of 2 numbers is 871 both numbers are even and they are not divisible by each other What is the smallest that these two numbers could be?

This problem doesn't work. If both numbers have a common factor of 871 and are even, that means they also have a common factor of 2. 5226 and 3484 are both even and have a common factor of 871 and are not divisible by each other, but their GCF is 1742 (2 x 871)
