What two numbers have a GCF of 998?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 998.

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 998. Below is the beginning list of multiples of 998 (1 through 7) in numerical order.

1. 998
2. 1996
3. 2994
4. 3992
5. 4990
6. 5988
7. 6986
etc...

Two numbers that have a GCF of 998 can be 998 and any other number on the list above. Thus, two numbers that have a GCF of 998 are:

998 & 1996
998 & 2994
998 & 3992
etc...

That is not all! Any combination of any multiple of 998 and "odd" multiples of 998 will also have GCF of 998. 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 998.

1996 & 2994
1996 & 4990
3992 & 4990
3992 & 6986
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 998. The lists we created can go on forever.
