What two numbers have a GCF of 2440?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2440.

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 2440. Below is the beginning list of multiples of 2440 (1 through 7) in numerical order.

1. 2440
2. 4880
3. 7320
4. 9760
5. 12200
6. 14640
7. 17080
etc...

Two numbers that have a GCF of 2440 can be 2440 and any other number on the list above. Thus, two numbers that have a GCF of 2440 are:

2440 & 4880
2440 & 7320
2440 & 9760
etc...

That is not all! Any combination of any multiple of 2440 and "odd" multiples of 2440 will also have GCF of 2440. 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 2440.

4880 & 7320
4880 & 12200
9760 & 12200
9760 & 17080
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2440. The lists we created can go on forever.
