What two numbers have a GCF of 518?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 518.

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 518. Below is the beginning list of multiples of 518 (1 through 7) in numerical order.

1. 518
2. 1036
3. 1554
4. 2072
5. 2590
6. 3108
7. 3626
etc...

Two numbers that have a GCF of 518 can be 518 and any other number on the list above. Thus, two numbers that have a GCF of 518 are:

518 & 1036
518 & 1554
518 & 2072
etc...

That is not all! Any combination of any multiple of 518 and "odd" multiples of 518 will also have GCF of 518. 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 518.

1036 & 1554
1036 & 2590
2072 & 2590
2072 & 3626
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 518. The lists we created can go on forever.
