What two numbers have a GCF of 765?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 765.

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 765. Below is the beginning list of multiples of 765 (1 through 7) in numerical order.

1. 765
2. 1530
3. 2295
4. 3060
5. 3825
6. 4590
7. 5355
etc...

Two numbers that have a GCF of 765 can be 765 and any other number on the list above. Thus, two numbers that have a GCF of 765 are:

765 & 1530
765 & 2295
765 & 3060
etc...

That is not all! Any combination of any multiple of 765 and "odd" multiples of 765 will also have GCF of 765. 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 765.

1530 & 2295
1530 & 3825
3060 & 3825
3060 & 5355
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 765. The lists we created can go on forever.
