What two numbers have a GCF of 2409?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2409.

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 2409. Below is the beginning list of multiples of 2409 (1 through 7) in numerical order.

1. 2409
2. 4818
3. 7227
4. 9636
5. 12045
6. 14454
7. 16863
etc...

Two numbers that have a GCF of 2409 can be 2409 and any other number on the list above. Thus, two numbers that have a GCF of 2409 are:

2409 & 4818
2409 & 7227
2409 & 9636
etc...

That is not all! Any combination of any multiple of 2409 and "odd" multiples of 2409 will also have GCF of 2409. 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 2409.

4818 & 7227
4818 & 12045
9636 & 12045
9636 & 16863
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2409. The lists we created can go on forever.
