What two numbers have a GCF of 1659?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1659.

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 1659. Below is the beginning list of multiples of 1659 (1 through 7) in numerical order.

1. 1659
2. 3318
3. 4977
4. 6636
5. 8295
6. 9954
7. 11613
etc...

Two numbers that have a GCF of 1659 can be 1659 and any other number on the list above. Thus, two numbers that have a GCF of 1659 are:

1659 & 3318
1659 & 4977
1659 & 6636
etc...

That is not all! Any combination of any multiple of 1659 and "odd" multiples of 1659 will also have GCF of 1659. 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 1659.

3318 & 4977
3318 & 8295
6636 & 8295
6636 & 11613
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1659. The lists we created can go on forever.
