What two numbers have a GCF of 1995?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1995.

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 1995. Below is the beginning list of multiples of 1995 (1 through 7) in numerical order.

1. 1995
2. 3990
3. 5985
4. 7980
5. 9975
6. 11970
7. 13965
etc...

Two numbers that have a GCF of 1995 can be 1995 and any other number on the list above. Thus, two numbers that have a GCF of 1995 are:

1995 & 3990
1995 & 5985
1995 & 7980
etc...

That is not all! Any combination of any multiple of 1995 and "odd" multiples of 1995 will also have GCF of 1995. 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 1995.

3990 & 5985
3990 & 9975
7980 & 9975
7980 & 13965
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1995. The lists we created can go on forever.
