What two numbers have a GCF of 1983?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1983.

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 1983. Below is the beginning list of multiples of 1983 (1 through 7) in numerical order.

1. 1983
2. 3966
3. 5949
4. 7932
5. 9915
6. 11898
7. 13881
etc...

Two numbers that have a GCF of 1983 can be 1983 and any other number on the list above. Thus, two numbers that have a GCF of 1983 are:

1983 & 3966
1983 & 5949
1983 & 7932
etc...

That is not all! Any combination of any multiple of 1983 and "odd" multiples of 1983 will also have GCF of 1983. 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 1983.

3966 & 5949
3966 & 9915
7932 & 9915
7932 & 13881
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1983. The lists we created can go on forever.
