What two numbers have a GCF of 2870?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2870.

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 2870. Below is the beginning list of multiples of 2870 (1 through 7) in numerical order.

1. 2870
2. 5740
3. 8610
4. 11480
5. 14350
6. 17220
7. 20090
etc...

Two numbers that have a GCF of 2870 can be 2870 and any other number on the list above. Thus, two numbers that have a GCF of 2870 are:

2870 & 5740
2870 & 8610
2870 & 11480
etc...

That is not all! Any combination of any multiple of 2870 and "odd" multiples of 2870 will also have GCF of 2870. 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 2870.

5740 & 8610
5740 & 14350
11480 & 14350
11480 & 20090
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2870. The lists we created can go on forever.
