What two numbers have a GCF of 1939?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1939.

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 1939. Below is the beginning list of multiples of 1939 (1 through 7) in numerical order.

1. 1939

6. 11634
7. 13573
etc...

Two numbers that have a GCF of 1939 can be 1939 and any other number on the list above. Thus, two numbers that have a GCF of 1939 are:

1939 & 3878
1939 & 5817

etc...

That is not all! Any combination of any multiple of 1939 and "odd" multiples of 1939 will also have GCF of 1939. We numbered the multiples above so it would be easy to identify the "odd" multiples (number 1, 3, 5, 7, etc). Thus, here are some more examples of two numbers that also have a GCF of 1939.

3878 & 5817
3878 & 9695
