What two numbers have a GCF of 9940?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 9940.

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 9940. Below is the beginning list of multiples of 9940 (1 through 7) in numerical order.

1. 9940
2. 19880
3. 29820
4. 39760
5. 49700
6. 59640
7. 69580
etc...

Two numbers that have a GCF of 9940 can be 9940 and any other number on the list above. Thus, two numbers that have a GCF of 9940 are:

9940 & 19880
9940 & 29820
9940 & 39760
etc...

That is not all! Any combination of any multiple of 9940 and "odd" multiples of 9940 will also have GCF of 9940. 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 9940.

19880 & 29820
19880 & 49700
39760 & 49700
39760 & 69580
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 9940. The lists we created can go on forever.
