What two numbers have a GCF of 2521?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2521.

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 2521. Below is the beginning list of multiples of 2521 (1 through 7) in numerical order.

1. 2521
2. 5042
3. 7563
4. 10084
5. 12605
6. 15126
7. 17647
etc...

Two numbers that have a GCF of 2521 can be 2521 and any other number on the list above. Thus, two numbers that have a GCF of 2521 are:

2521 & 5042
2521 & 7563
2521 & 10084
etc...

That is not all! Any combination of any multiple of 2521 and "odd" multiples of 2521 will also have GCF of 2521. 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 2521.

5042 & 7563
5042 & 12605
10084 & 12605
10084 & 17647
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2521. The lists we created can go on forever.
