How can you find the gcf and common factors?

List the prime factors of each number.Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
GCF and common factors are pretty much the same thing. GCF focuses only on the largest common while common focuses on them all.

Since the their sum is 37, the two consecutive integers are 18 and 19. I Hope This Helped! :)
