What two numbers have a GCF of 5280?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 5280.

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 5280. Below is the beginning list of multiples of 5280 (1 through 7) in numerical order.

1. 5280
2. 10560
3. 15840
4. 21120
5. 26400
6. 31680
7. 36960
etc...

Two numbers that have a GCF of 5280 can be 5280 and any other number on the list above. Thus, two numbers that have a GCF of 5280 are:

5280 & 10560
5280 & 15840
5280 & 21120
etc...

That is not all! Any combination of any multiple of 5280 and "odd" multiples of 5280 will also have GCF of 5280. 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 5280.

10560 & 15840
10560 & 26400
21120 & 26400
21120 & 36960
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 5280. The lists we created can go on forever.
