What two numbers have a GCF of 540?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 540.

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 540. Below is the beginning list of multiples of 540 (1 through 7) in numerical order.

1. 540
2. 1080
3. 1620
4. 2160
5. 2700
6. 3240
7. 3780
etc...

Two numbers that have a GCF of 540 can be 540 and any other number on the list above. Thus, two numbers that have a GCF of 540 are:

540 & 1080
540 & 1620
540 & 2160
etc...

That is not all! Any combination of any multiple of 540 and "odd" multiples of 540 will also have GCF of 540. 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 540.

1080 & 1620
1080 & 2700
2160 & 2700
2160 & 3780
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 540. The lists we created can go on forever.
