What two numbers have a GCF of 617?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 617.

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 617. Below is the beginning list of multiples of 617 (1 through 7) in numerical order.

1. 617
2. 1234
3. 1851
4. 2468
5. 3085
6. 3702
7. 4319
etc...

Two numbers that have a GCF of 617 can be 617 and any other number on the list above. Thus, two numbers that have a GCF of 617 are:

617 & 1234
617 & 1851
617 & 2468
etc...

That is not all! Any combination of any multiple of 617 and "odd" multiples of 617 will also have GCF of 617. 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 617.

1234 & 1851
1234 & 3085
2468 & 3085
2468 & 4319
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 617. The lists we created can go on forever.
