What two numbers have a GCF of 634?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 634.

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 634. Below is the beginning list of multiples of 634 (1 through 7) in numerical order.

1. 634
2. 1268
3. 1902
4. 2536
5. 3170
6. 3804
7. 4438
etc...

Two numbers that have a GCF of 634 can be 634 and any other number on the list above. Thus, two numbers that have a GCF of 634 are:

634 & 1268
634 & 1902
634 & 2536
etc...

That is not all! Any combination of any multiple of 634 and "odd" multiples of 634 will also have GCF of 634. 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 634.

1268 & 1902
1268 & 3170
2536 & 3170
2536 & 4438
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 634. The lists we created can go on forever.
