What two numbers have a GCF of 681?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 681.

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 681. Below is the beginning list of multiples of 681 (1 through 7) in numerical order.

1. 681
2. 1362
3. 2043
4. 2724
5. 3405
6. 4086
7. 4767
etc...

Two numbers that have a GCF of 681 can be 681 and any other number on the list above. Thus, two numbers that have a GCF of 681 are:

681 & 1362
681 & 2043
681 & 2724
etc...

That is not all! Any combination of any multiple of 681 and "odd" multiples of 681 will also have GCF of 681. 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 681.

1362 & 2043
1362 & 3405
2724 & 3405
2724 & 4767
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 681. The lists we created can go on forever.
