What two numbers have a GCF of 816?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 816.

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 816. Below is the beginning list of multiples of 816 (1 through 7) in numerical order.

1. 816
2. 1632
3. 2448
4. 3264
5. 4080
6. 4896
7. 5712
etc...

Two numbers that have a GCF of 816 can be 816 and any other number on the list above. Thus, two numbers that have a GCF of 816 are:

816 & 1632
816 & 2448
816 & 3264
etc...

That is not all! Any combination of any multiple of 816 and "odd" multiples of 816 will also have GCF of 816. 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 816.

1632 & 2448
1632 & 4080
3264 & 4080
3264 & 5712
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 816. The lists we created can go on forever.
