What two numbers have a GCF of 1899?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1899.

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 1899. Below is the beginning list of multiples of 1899 (1 through 7) in numerical order.

1. 1899
2. 3798
3. 5697
4. 7596
5. 9495
6. 11394
7. 13293
etc...

Two numbers that have a GCF of 1899 can be 1899 and any other number on the list above. Thus, two numbers that have a GCF of 1899 are:

1899 & 3798
1899 & 5697
1899 & 7596
etc...

That is not all! Any combination of any multiple of 1899 and "odd" multiples of 1899 will also have GCF of 1899. 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 1899.

3798 & 5697
3798 & 9495
7596 & 9495
7596 & 13293
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1899. The lists we created can go on forever.
