What two numbers have a GCF of 790?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 790.

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 790. Below is the beginning list of multiples of 790 (1 through 7) in numerical order.

1. 790
2. 1580
3. 2370
4. 3160
5. 3950
6. 4740
7. 5530
etc...

Two numbers that have a GCF of 790 can be 790 and any other number on the list above. Thus, two numbers that have a GCF of 790 are:

790 & 1580
790 & 2370
790 & 3160
etc...

That is not all! Any combination of any multiple of 790 and "odd" multiples of 790 will also have GCF of 790. 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 790.

1580 & 2370
1580 & 3950
3160 & 3950
3160 & 5530
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 790. The lists we created can go on forever.
