What two numbers have a GCF of 865?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 865.

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 865. Below is the beginning list of multiples of 865 (1 through 7) in numerical order.

1. 865
2. 1730
3. 2595
4. 3460
5. 4325
6. 5190
7. 6055
etc...

Two numbers that have a GCF of 865 can be 865 and any other number on the list above. Thus, two numbers that have a GCF of 865 are:

865 & 1730
865 & 2595
865 & 3460
etc...

That is not all! Any combination of any multiple of 865 and "odd" multiples of 865 will also have GCF of 865. 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 865.

1730 & 2595
1730 & 4325
3460 & 4325
3460 & 6055
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 865. The lists we created can go on forever.
