What two numbers have a GCF of 828?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 828.

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 828. Below is the beginning list of multiples of 828 (1 through 7) in numerical order.

1. 828
2. 1656
3. 2484
4. 3312
5. 4140
6. 4968
7. 5796
etc...

Two numbers that have a GCF of 828 can be 828 and any other number on the list above. Thus, two numbers that have a GCF of 828 are:

828 & 1656
828 & 2484
828 & 3312
etc...

That is not all! Any combination of any multiple of 828 and "odd" multiples of 828 will also have GCF of 828. 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 828.

1656 & 2484
1656 & 4140
3312 & 4140
3312 & 5796
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 828. The lists we created can go on forever.
