What two numbers have a GCF of 2139?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2139.

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 2139. Below is the beginning list of multiples of 2139 (1 through 7) in numerical order.

1. 2139
2. 4278
3. 6417
4. 8556
5. 10695
6. 12834
7. 14973
etc...

Two numbers that have a GCF of 2139 can be 2139 and any other number on the list above. Thus, two numbers that have a GCF of 2139 are:

2139 & 4278
2139 & 6417
2139 & 8556
etc...

That is not all! Any combination of any multiple of 2139 and "odd" multiples of 2139 will also have GCF of 2139. 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 2139.

4278 & 6417
4278 & 10695
8556 & 10695
8556 & 14973
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2139. The lists we created can go on forever.
