What two numbers have a GCF of 981?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 981.

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 981. Below is the beginning list of multiples of 981 (1 through 7) in numerical order.

1. 981
2. 1962
3. 2943
4. 3924
5. 4905
6. 5886
7. 6867
etc...

Two numbers that have a GCF of 981 can be 981 and any other number on the list above. Thus, two numbers that have a GCF of 981 are:

981 & 1962
981 & 2943
981 & 3924
etc...

That is not all! Any combination of any multiple of 981 and "odd" multiples of 981 will also have GCF of 981. 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 981.

1962 & 2943
1962 & 4905
3924 & 4905
3924 & 6867
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 981. The lists we created can go on forever.
