What two numbers have a GCF of 2190?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2190.

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 2190. Below is the beginning list of multiples of 2190 (1 through 7) in numerical order.

1. 2190
2. 4380
3. 6570
4. 8760
5. 10950
6. 13140
7. 15330
etc...

Two numbers that have a GCF of 2190 can be 2190 and any other number on the list above. Thus, two numbers that have a GCF of 2190 are:

2190 & 4380
2190 & 6570
2190 & 8760
etc...

That is not all! Any combination of any multiple of 2190 and "odd" multiples of 2190 will also have GCF of 2190. 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 2190.

4380 & 6570
4380 & 10950
8760 & 10950
8760 & 15330
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2190. The lists we created can go on forever.
