What two numbers have a GCF of 1655?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1655.

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 1655. Below is the beginning list of multiples of 1655 (1 through 7) in numerical order.

1. 1655
2. 3310
3. 4965
4. 6620
5. 8275
6. 9930
7. 11585
etc...

Two numbers that have a GCF of 1655 can be 1655 and any other number on the list above. Thus, two numbers that have a GCF of 1655 are:

1655 & 3310
1655 & 4965
1655 & 6620
etc...

That is not all! Any combination of any multiple of 1655 and "odd" multiples of 1655 will also have GCF of 1655. 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 1655.

3310 & 4965
3310 & 8275
6620 & 8275
6620 & 11585
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1655. The lists we created can go on forever.
