What two numbers have a GCF of 1397?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1397.

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 1397. Below is the beginning list of multiples of 1397 (1 through 7) in numerical order.

1. 1397
2. 2794
3. 4191
4. 5588
5. 6985
6. 8382
7. 9779
etc...

Two numbers that have a GCF of 1397 can be 1397 and any other number on the list above. Thus, two numbers that have a GCF of 1397 are:

1397 & 2794
1397 & 4191
1397 & 5588
etc...

That is not all! Any combination of any multiple of 1397 and "odd" multiples of 1397 will also have GCF of 1397. 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 1397.

2794 & 4191
2794 & 6985
5588 & 6985
5588 & 9779
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1397. The lists we created can go on forever.
