What two numbers have a GCF of 2439?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2439.

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 2439. Below is the beginning list of multiples of 2439 (1 through 7) in numerical order.

1. 2439
2. 4878
3. 7317
4. 9756
5. 12195
6. 14634
7. 17073
etc...

Two numbers that have a GCF of 2439 can be 2439 and any other number on the list above. Thus, two numbers that have a GCF of 2439 are:

2439 & 4878
2439 & 7317
2439 & 9756
etc...

That is not all! Any combination of any multiple of 2439 and "odd" multiples of 2439 will also have GCF of 2439. 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 2439.

4878 & 7317
4878 & 12195
9756 & 12195
9756 & 17073
etc...
