What two numbers have a GCF of 1878?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1878.

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 1878. Below is the beginning list of multiples of 1878 (1 through 7) in numerical order.

1. 1878
2. 3756
3. 5634
4. 7512
5. 9390
6. 11268
7. 13146
etc...

Two numbers that have a GCF of 1878 can be 1878 and any other number on the list above. Thus, two numbers that have a GCF of 1878 are:

1878 & 3756
1878 & 5634
1878 & 7512
etc...

That is not all! Any combination of any multiple of 1878 and "odd" multiples of 1878 will also have GCF of 1878. 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 1878.

3756 & 5634
3756 & 9390
7512 & 9390
7512 & 13146
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1878. The lists we created can go on forever.
