What two numbers have a GCF of 2121?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2121.

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 2121. Below is the beginning list of multiples of 2121 (1 through 7) in numerical order.

1. 2121
2. 4242
3. 6363
4. 8484
5. 10605
6. 12726
7. 14847
etc...

Two numbers that have a GCF of 2121 can be 2121 and any other number on the list above. Thus, two numbers that have a GCF of 2121 are:

2121 & 4242
2121 & 6363
2121 & 8484
etc...

That is not all! Any combination of any multiple of 2121 and "odd" multiples of 2121 will also have GCF of 2121. 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 2121.

4242 & 6363
4242 & 10605
8484 & 10605
8484 & 14847
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2121. The lists we created can go on forever.
