What two numbers have a GCF of 2978?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2978.

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 2978. Below is the beginning list of multiples of 2978 (1 through 7) in numerical order.

1. 2978
2. 5956
3. 8934
4. 11912
5. 14890
6. 17868
7. 20846
etc...

Two numbers that have a GCF of 2978 can be 2978 and any other number on the list above. Thus, two numbers that have a GCF of 2978 are:

2978 & 5956
2978 & 8934
2978 & 11912
etc...

That is not all! Any combination of any multiple of 2978 and "odd" multiples of 2978 will also have GCF of 2978. 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 2978.

5956 & 8934
5956 & 14890
11912 & 14890
11912 & 20846
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2978. The lists we created can go on forever.
