What two numbers have a GCF of 1988?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1988.

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 1988. Below is the beginning list of multiples of 1988 (1 through 7) in numerical order.

1. 1988
2. 3976
3. 5964
4. 7952
5. 9940
6. 11928
7. 13916
etc...

Two numbers that have a GCF of 1988 can be 1988 and any other number on the list above. Thus, two numbers that have a GCF of 1988 are:

1988 & 3976
1988 & 5964
1988 & 7952
etc...

That is not all! Any combination of any multiple of 1988 and "odd" multiples of 1988 will also have GCF of 1988. 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 1988.

3976 & 5964
3976 & 9940
7952 & 9940
7952 & 13916
etc...
