What two numbers have a GCF of 987?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 987.

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 987. Below is the beginning list of multiples of 987 (1 through 7) in numerical order.

1. 987
2. 1974
3. 2961
4. 3948
5. 4935
6. 5922
7. 6909
etc...

Two numbers that have a GCF of 987 can be 987 and any other number on the list above. Thus, two numbers that have a GCF of 987 are:

987 & 1974
987 & 2961
987 & 3948
etc...

That is not all! Any combination of any multiple of 987 and "odd" multiples of 987 will also have GCF of 987. 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 987.

1974 & 2961
1974 & 4935
3948 & 4935
3948 & 6909
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 987. The lists we created can go on forever.
