What two numbers have a GCF of 1689?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1689.

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 1689. Below is the beginning list of multiples of 1689 (1 through 7) in numerical order.

1. 1689
2. 3378
3. 5067
4. 6756
5. 8445
6. 10134
7. 11823
etc...

Two numbers that have a GCF of 1689 can be 1689 and any other number on the list above. Thus, two numbers that have a GCF of 1689 are:

1689 & 3378
1689 & 5067
1689 & 6756
etc...

That is not all! Any combination of any multiple of 1689 and "odd" multiples of 1689 will also have GCF of 1689. 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 1689.

3378 & 5067
3378 & 8445
6756 & 8445
6756 & 11823
etc...
