What two numbers have a GCF of 7680?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 7680.

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 7680. Below is the beginning list of multiples of 7680 (1 through 7) in numerical order.

1. 7680
2. 15360
3. 23040
4. 30720
5. 38400
6. 46080
7. 53760
etc...

Two numbers that have a GCF of 7680 can be 7680 and any other number on the list above. Thus, two numbers that have a GCF of 7680 are:

7680 & 15360
7680 & 23040
7680 & 30720
etc...

That is not all! Any combination of any multiple of 7680 and "odd" multiples of 7680 will also have GCF of 7680. 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 7680.

15360 & 23040
15360 & 38400
30720 & 38400
30720 & 53760
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 7680. The lists we created can go on forever.
