What two numbers have a GCF of 1785?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1785.

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 1785. Below is the beginning list of multiples of 1785 (1 through 7) in numerical order.

1. 1785
2. 3570
3. 5355
4. 7140
5. 8925
6. 10710
7. 12495
etc...

Two numbers that have a GCF of 1785 can be 1785 and any other number on the list above. Thus, two numbers that have a GCF of 1785 are:

1785 & 3570
1785 & 5355
1785 & 7140
etc...

That is not all! Any combination of any multiple of 1785 and "odd" multiples of 1785 will also have GCF of 1785. 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 1785.

3570 & 5355
3570 & 8925
7140 & 8925
7140 & 12495
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1785. The lists we created can go on forever.
