What two numbers have a GCF of 135?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 135.

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 135. Below is the beginning list of multiples of 135 (1 through 7) in numerical order.

1. 135
2. 270
3. 405
4. 540
5. 675
6. 810
7. 945
etc...

Two numbers that have a GCF of 135 can be 135 and any other number on the list above. Thus, two numbers that have a GCF of 135 are:

135 & 270
135 & 405
135 & 540
etc...

That is not all! Any combination of any multiple of 135 and "odd" multiples of 135 will also have GCF of 135. 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 135.

270 & 405
270 & 675
540 & 675
540 & 945
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 135. The lists we created can go on forever.
