What two numbers have a GCF of 1872?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1872.

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 1872. Below is the beginning list of multiples of 1872 (1 through 7) in numerical order.

1. 1872
2. 3744
3. 5616
4. 7488
5. 9360
6. 11232
7. 13104
etc...

Two numbers that have a GCF of 1872 can be 1872 and any other number on the list above. Thus, two numbers that have a GCF of 1872 are:

1872 & 3744
1872 & 5616
1872 & 7488
etc...

That is not all! Any combination of any multiple of 1872 and "odd" multiples of 1872 will also have GCF of 1872. 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 1872.

3744 & 5616
3744 & 9360
7488 & 9360
7488 & 13104
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1872. The lists we created can go on forever.
