What two numbers have a GCF of 4321?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 4321.

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 4321. Below is the beginning list of multiples of 4321 (1 through 7) in numerical order.

1. 4321
2. 8642
3. 12963
4. 17284
5. 21605
6. 25926
7. 30247
etc...

Two numbers that have a GCF of 4321 can be 4321 and any other number on the list above. Thus, two numbers that have a GCF of 4321 are:

4321 & 8642
4321 & 12963
4321 & 17284
etc...

That is not all! Any combination of any multiple of 4321 and "odd" multiples of 4321 will also have GCF of 4321. 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 4321.

8642 & 12963
8642 & 21605
17284 & 21605
17284 & 30247
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 4321. The lists we created can go on forever.
