What two numbers have a GCF of 1365?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1365.

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 1365. Below is the beginning list of multiples of 1365 (1 through 7) in numerical order.

1. 1365
2. 2730
3. 4095
4. 5460
5. 6825
6. 8190
7. 9555
etc...

Two numbers that have a GCF of 1365 can be 1365 and any other number on the list above. Thus, two numbers that have a GCF of 1365 are:

1365 & 2730
1365 & 4095
1365 & 5460
etc...

That is not all! Any combination of any multiple of 1365 and "odd" multiples of 1365 will also have GCF of 1365. 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 1365.

2730 & 4095
2730 & 6825
5460 & 6825
5460 & 9555
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1365. The lists we created can go on forever.
