What two numbers have a GCF of 2490?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2490.

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 2490. Below is the beginning list of multiples of 2490 (1 through 7) in numerical order.

1. 2490
2. 4980
3. 7470
4. 9960
5. 12450
6. 14940
7. 17430
etc...

Two numbers that have a GCF of 2490 can be 2490 and any other number on the list above. Thus, two numbers that have a GCF of 2490 are:

2490 & 4980
2490 & 7470
2490 & 9960
etc...

That is not all! Any combination of any multiple of 2490 and "odd" multiples of 2490 will also have GCF of 2490. 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 2490.

4980 & 7470
4980 & 12450
9960 & 12450
9960 & 17430
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2490. The lists we created can go on forever.
