What two numbers have a GCF of 2391?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2391.

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 2391. Below is the beginning list of multiples of 2391 (1 through 7) in numerical order.

1. 2391
2. 4782
3. 7173
4. 9564
5. 11955
6. 14346
7. 16737
etc...

Two numbers that have a GCF of 2391 can be 2391 and any other number on the list above. Thus, two numbers that have a GCF of 2391 are:

2391 & 4782
2391 & 7173
2391 & 9564
etc...

That is not all! Any combination of any multiple of 2391 and "odd" multiples of 2391 will also have GCF of 2391. 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 2391.

4782 & 7173
4782 & 11955
9564 & 11955
9564 & 16737
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2391. The lists we created can go on forever.
