What two numbers have a GCF of 1985?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1985.

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 1985. Below is the beginning list of multiples of 1985 (1 through 7) in numerical order.

1. 1985
2. 3970
3. 5955
4. 7940
5. 9925
6. 11910
7. 13895
etc...

Two numbers that have a GCF of 1985 can be 1985 and any other number on the list above. Thus, two numbers that have a GCF of 1985 are:

1985 & 3970
1985 & 5955
1985 & 7940
etc...

That is not all! Any combination of any multiple of 1985 and "odd" multiples of 1985 will also have GCF of 1985. 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 1985.

3970 & 5955
3970 & 9925
7940 & 9925
7940 & 13895
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1985. The lists we created can go on forever.
