What two numbers have a GCF of 2140?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2140.

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 2140. Below is the beginning list of multiples of 2140 (1 through 7) in numerical order.

1. 2140
2. 4280
3. 6420
4. 8560
5. 10700
6. 12840
7. 14980
etc...

Two numbers that have a GCF of 2140 can be 2140 and any other number on the list above. Thus, two numbers that have a GCF of 2140 are:

2140 & 4280
2140 & 6420
2140 & 8560
etc...

That is not all! Any combination of any multiple of 2140 and "odd" multiples of 2140 will also have GCF of 2140. 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 2140.

4280 & 6420
4280 & 10700
8560 & 10700
8560 & 14980
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2140. The lists we created can go on forever.
