What two numbers have a GCF of 3128?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 3128.

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 3128. Below is the beginning list of multiples of 3128 (1 through 7) in numerical order.

1. 3128
2. 6256
3. 9384
4. 12512
5. 15640
6. 18768
7. 21896
etc...

Two numbers that have a GCF of 3128 can be 3128 and any other number on the list above. Thus, two numbers that have a GCF of 3128 are:

3128 & 6256
3128 & 9384
3128 & 12512
etc...

That is not all! Any combination of any multiple of 3128 and "odd" multiples of 3128 will also have GCF of 3128. 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 3128.

6256 & 9384
6256 & 15640
12512 & 15640
12512 & 21896
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 3128. The lists we created can go on forever.
