What two numbers have a GCF of 785?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 785.

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 785. Below is the beginning list of multiples of 785 (1 through 7) in numerical order.

1. 785
2. 1570
3. 2355
4. 3140
5. 3925
6. 4710
7. 5495
etc...

Two numbers that have a GCF of 785 can be 785 and any other number on the list above. Thus, two numbers that have a GCF of 785 are:

785 & 1570
785 & 2355
785 & 3140
etc...

That is not all! Any combination of any multiple of 785 and "odd" multiples of 785 will also have GCF of 785. 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 785.

1570 & 2355
1570 & 3925
3140 & 3925
3140 & 5495
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 785. The lists we created can go on forever.
