What two numbers have a GCF of 115?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 115.

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 115. Below is the beginning list of multiples of 115 (1 through 7) in numerical order.

1. 115
2. 230
3. 345
4. 460
5. 575
6. 690
7. 805
etc...

Two numbers that have a GCF of 115 can be 115 and any other number on the list above. Thus, two numbers that have a GCF of 115 are:

115 & 230
115 & 345
115 & 460
etc...

That is not all! Any combination of any multiple of 115 and "odd" multiples of 115 will also have GCF of 115. 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 115.

230 & 345
230 & 575
460 & 575
460 & 805
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 115. The lists we created can go on forever.
