What two numbers have a GCF of 1656?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1656.

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 1656. Below is the beginning list of multiples of 1656 (1 through 7) in numerical order.

1. 1656
2. 3312
3. 4968
4. 6624
5. 8280
6. 9936
7. 11592
etc...

Two numbers that have a GCF of 1656 can be 1656 and any other number on the list above. Thus, two numbers that have a GCF of 1656 are:

1656 & 3312
1656 & 4968
1656 & 6624
etc...

That is not all! Any combination of any multiple of 1656 and "odd" multiples of 1656 will also have GCF of 1656. 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 1656.

3312 & 4968
3312 & 8280
6624 & 8280
6624 & 11592
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1656. The lists we created can go on forever.
