What two numbers have a GCF of 130?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 130.

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 130. Below is the beginning list of multiples of 130 (1 through 7) in numerical order.

1. 130
2. 260
3. 390
4. 520
5. 650
6. 780
7. 910
etc...

Two numbers that have a GCF of 130 can be 130 and any other number on the list above. Thus, two numbers that have a GCF of 130 are:

130 & 260
130 & 390
130 & 520
etc...

That is not all! Any combination of any multiple of 130 and "odd" multiples of 130 will also have GCF of 130. 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 130.

260 & 390
260 & 650
520 & 650
520 & 910
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 130. The lists we created can go on forever.
