What two numbers have a GCF of 656?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 656.

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 656. Below is the beginning list of multiples of 656 (1 through 7) in numerical order.

1. 656
2. 1312
3. 1968
4. 2624
5. 3280
6. 3936
7. 4592
etc...

Two numbers that have a GCF of 656 can be 656 and any other number on the list above. Thus, two numbers that have a GCF of 656 are:

656 & 1312
656 & 1968
656 & 2624
etc...

That is not all! Any combination of any multiple of 656 and "odd" multiples of 656 will also have GCF of 656. 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 656.

1312 & 1968
1312 & 3280
2624 & 3280
2624 & 4592
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 656. The lists we created can go on forever.
