What two numbers have a GCF of 9729?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 9729.

There is actually an infinite number of answers to this question. First, note that both the numbers we are looking for must be multiples of 9729. Below is the beginning list of multiples of 9729 (1 through 7) in numerical order.
