What two numbers have a GCF of 1255?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1255.

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 1255. Below is the beginning list of multiples of 1255 (1 through 7) in numerical order.

1. 1255
2. 2510
3. 3765
4. 5020
5. 6275
6. 7530
7. 8785
etc...

Two numbers that have a GCF of 1255 can be 1255 and any other number on the list above. Thus, two numbers that have a GCF of 1255 are:

1255 & 2510
1255 & 3765
1255 & 5020
etc...

That is not all! Any combination of any multiple of 1255 and "odd" multiples of 1255 will also have GCF of 1255. 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 1255.

2510 & 3765
2510 & 6275
5020 & 6275
5020 & 8785
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1255. The lists we created can go on forever.
