What two numbers have a GCF of 270?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 270.

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 270. Below is the beginning list of multiples of 270 (1 through 7) in numerical order.

1. 270
2. 540
3. 810
4. 1080
5. 1350
6. 1620
7. 1890
etc...

Two numbers that have a GCF of 270 can be 270 and any other number on the list above. Thus, two numbers that have a GCF of 270 are:

270 & 540
270 & 810
270 & 1080
etc...

That is not all! Any combination of any multiple of 270 and "odd" multiples of 270 will also have GCF of 270. 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 270.

540 & 810
540 & 1350
1080 & 1350
1080 & 1890
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 270. The lists we created can go on forever.
