What two numbers have a GCF of 260?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 260.

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 260. Below is the beginning list of multiples of 260 (1 through 7) in numerical order.

1. 260
2. 520
3. 780
4. 1040
5. 1300
6. 1560
7. 1820
etc...

Two numbers that have a GCF of 260 can be 260 and any other number on the list above. Thus, two numbers that have a GCF of 260 are:

260 & 520
260 & 780
260 & 1040
etc...

That is not all! Any combination of any multiple of 260 and "odd" multiples of 260 will also have GCF of 260. 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 260.

520 & 780
520 & 1300
1040 & 1300
1040 & 1820
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 260. The lists we created can go on forever.
