What two numbers have a GCF of 1644?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1644.

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 1644. Below is the beginning list of multiples of 1644 (1 through 7) in numerical order.

1. 1644
2. 3288
3. 4932
4. 6576
5. 8220
6. 9864
7. 11508
etc...

Two numbers that have a GCF of 1644 can be 1644 and any other number on the list above. Thus, two numbers that have a GCF of 1644 are:

1644 & 3288
1644 & 4932
1644 & 6576
etc...

That is not all! Any combination of any multiple of 1644 and "odd" multiples of 1644 will also have GCF of 1644. 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 1644.

3288 & 4932
3288 & 8220
6576 & 8220
6576 & 11508
etc...
