What two numbers have a GCF of 813?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 813.

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 813. Below is the beginning list of multiples of 813 (1 through 7) in numerical order.

1. 813
2. 1626
3. 2439
4. 3252
5. 4065
6. 4878
7. 5691
etc...

Two numbers that have a GCF of 813 can be 813 and any other number on the list above. Thus, two numbers that have a GCF of 813 are:

813 & 1626
813 & 2439
813 & 3252
etc...

That is not all! Any combination of any multiple of 813 and "odd" multiples of 813 will also have GCF of 813. 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 813.

1626 & 2439
1626 & 4065
3252 & 4065
3252 & 5691
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 813. The lists we created can go on forever.
