What two numbers have a GCF of 1805?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1805.

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 1805. Below is the beginning list of multiples of 1805 (1 through 7) in numerical order.

1. 1805
2. 3610
3. 5415
4. 7220
5. 9025
6. 10830
7. 12635
etc...

Two numbers that have a GCF of 1805 can be 1805 and any other number on the list above. Thus, two numbers that have a GCF of 1805 are:

1805 & 3610
1805 & 5415
1805 & 7220
etc...

That is not all! Any combination of any multiple of 1805 and "odd" multiples of 1805 will also have GCF of 1805. 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 1805.

3610 & 5415
3610 & 9025
7220 & 9025
7220 & 12635
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1805. The lists we created can go on forever.
