What two numbers have a GCF of 2605?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2605.

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 2605. Below is the beginning list of multiples of 2605 (1 through 7) in numerical order.

1. 2605
2. 5210
3. 7815
4. 10420
5. 13025
6. 15630
7. 18235
etc...

Two numbers that have a GCF of 2605 can be 2605 and any other number on the list above. Thus, two numbers that have a GCF of 2605 are:

2605 & 5210
2605 & 7815
2605 & 10420
etc...

That is not all! Any combination of any multiple of 2605 and "odd" multiples of 2605 will also have GCF of 2605. 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 2605.

5210 & 7815
5210 & 13025
10420 & 13025
10420 & 18235
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2605. The lists we created can go on forever.
