What two numbers have a GCF of 730?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 730.

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 730. Below is the beginning list of multiples of 730 (1 through 7) in numerical order.

1. 730
2. 1460
3. 2190
4. 2920
5. 3650
6. 4380
7. 5110
etc...

Two numbers that have a GCF of 730 can be 730 and any other number on the list above. Thus, two numbers that have a GCF of 730 are:

730 & 1460
730 & 2190
730 & 2920
etc...

That is not all! Any combination of any multiple of 730 and "odd" multiples of 730 will also have GCF of 730. 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 730.

1460 & 2190
1460 & 3650
2920 & 3650
2920 & 5110
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 730. The lists we created can go on forever.
