What two numbers have a GCF of 2389?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2389.

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 2389. Below is the beginning list of multiples of 2389 (1 through 7) in numerical order.

1. 2389
2. 4778
3. 7167
4. 9556
5. 11945
6. 14334
7. 16723
etc...

Two numbers that have a GCF of 2389 can be 2389 and any other number on the list above. Thus, two numbers that have a GCF of 2389 are:

2389 & 4778
2389 & 7167
2389 & 9556
etc...

That is not all! Any combination of any multiple of 2389 and "odd" multiples of 2389 will also have GCF of 2389. 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 2389.

4778 & 7167
4778 & 11945
9556 & 11945
9556 & 16723
etc...
