What two numbers have a GCF of 1399?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1399.

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 1399. Below is the beginning list of multiples of 1399 (1 through 7) in numerical order.

1. 1399
2. 2798
3. 4197
4. 5596
5. 6995
6. 8394
7. 9793
etc...

Two numbers that have a GCF of 1399 can be 1399 and any other number on the list above. Thus, two numbers that have a GCF of 1399 are:

1399 & 2798
1399 & 4197
1399 & 5596
etc...

That is not all! Any combination of any multiple of 1399 and "odd" multiples of 1399 will also have GCF of 1399. 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 1399.

2798 & 4197
2798 & 6995
5596 & 6995
5596 & 9793
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1399. The lists we created can go on forever.
