What two numbers have a GCF of 798?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 798.

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 798. Below is the beginning list of multiples of 798 (1 through 7) in numerical order.

1. 798
2. 1596
3. 2394
4. 3192
5. 3990
6. 4788
7. 5586
etc...

Two numbers that have a GCF of 798 can be 798 and any other number on the list above. Thus, two numbers that have a GCF of 798 are:

798 & 1596
798 & 2394
798 & 3192
etc...

That is not all! Any combination of any multiple of 798 and "odd" multiples of 798 will also have GCF of 798. 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 798.

1596 & 2394
1596 & 3990
3192 & 3990
3192 & 5586
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 798. The lists we created can go on forever.
