What two numbers have a GCF of 1904?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1904.

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 1904. Below is the beginning list of multiples of 1904 (1 through 7) in numerical order.

1. 1904
2. 3808
3. 5712
4. 7616
5. 9520
6. 11424
7. 13328
etc...

Two numbers that have a GCF of 1904 can be 1904 and any other number on the list above. Thus, two numbers that have a GCF of 1904 are:

1904 & 3808
1904 & 5712
1904 & 7616
etc...

That is not all! Any combination of any multiple of 1904 and "odd" multiples of 1904 will also have GCF of 1904. 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 1904.

3808 & 5712
3808 & 9520
7616 & 9520
7616 & 13328
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1904. The lists we created can go on forever.
