What two numbers have a GCF of 843?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 843.

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 843. Below is the beginning list of multiples of 843 (1 through 7) in numerical order.

1. 843
2. 1686
3. 2529
4. 3372
5. 4215
6. 5058
7. 5901
etc...

Two numbers that have a GCF of 843 can be 843 and any other number on the list above. Thus, two numbers that have a GCF of 843 are:

843 & 1686
843 & 2529
843 & 3372
etc...

That is not all! Any combination of any multiple of 843 and "odd" multiples of 843 will also have GCF of 843. 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 843.

1686 & 2529
1686 & 4215
3372 & 4215
3372 & 5901
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 843. The lists we created can go on forever.
