What two numbers have a GCF of 715?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 715.

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 715. Below is the beginning list of multiples of 715 (1 through 7) in numerical order.

1. 715
2. 1430
3. 2145
4. 2860
5. 3575
6. 4290
7. 5005
etc...

Two numbers that have a GCF of 715 can be 715 and any other number on the list above. Thus, two numbers that have a GCF of 715 are:

715 & 1430
715 & 2145
715 & 2860
etc...

That is not all! Any combination of any multiple of 715 and "odd" multiples of 715 will also have GCF of 715. 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 715.

1430 & 2145
1430 & 3575
2860 & 3575
2860 & 5005
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 715. The lists we created can go on forever.
