What two numbers have a GCF of 1646?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1646.

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 1646. Below is the beginning list of multiples of 1646 (1 through 7) in numerical order.

1. 1646
2. 3292
3. 4938
4. 6584
5. 8230
6. 9876
7. 11522
etc...

Two numbers that have a GCF of 1646 can be 1646 and any other number on the list above. Thus, two numbers that have a GCF of 1646 are:

1646 & 3292
1646 & 4938
1646 & 6584
etc...

That is not all! Any combination of any multiple of 1646 and "odd" multiples of 1646 will also have GCF of 1646. 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 1646.

3292 & 4938
3292 & 8230
6584 & 8230
6584 & 11522
etc...
