What two numbers have a GCF of 6721?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 6721.

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 6721. Below is the beginning list of multiples of 6721 (1 through 7) in numerical order.

1. 6721
2. 13442
3. 20163
4. 26884
5. 33605
6. 40326
7. 47047
etc...

Two numbers that have a GCF of 6721 can be 6721 and any other number on the list above. Thus, two numbers that have a GCF of 6721 are:

6721 & 13442
6721 & 20163
6721 & 26884
etc...

That is not all! Any combination of any multiple of 6721 and "odd" multiples of 6721 will also have GCF of 6721. 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 6721.

13442 & 20163
13442 & 33605
26884 & 33605
26884 & 47047
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 6721. The lists we created can go on forever.
