What two numbers have a GCF of 677?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 677.

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 677. Below is the beginning list of multiples of 677 (1 through 7) in numerical order.

1. 677
2. 1354
3. 2031
4. 2708
5. 3385
6. 4062
7. 4739
etc...

Two numbers that have a GCF of 677 can be 677 and any other number on the list above. Thus, two numbers that have a GCF of 677 are:

677 & 1354
677 & 2031
677 & 2708
etc...

That is not all! Any combination of any multiple of 677 and "odd" multiples of 677 will also have GCF of 677. 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 677.

1354 & 2031
1354 & 3385
2708 & 3385
2708 & 4739
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 677. The lists we created can go on forever.
