What two numbers have a GCF of 187?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 187.

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 187. Below is the beginning list of multiples of 187 (1 through 7) in numerical order.

1. 187
2. 374
3. 561
4. 748
5. 935
6. 1122
7. 1309
etc...

Two numbers that have a GCF of 187 can be 187 and any other number on the list above. Thus, two numbers that have a GCF of 187 are:

187 & 374
187 & 561
187 & 748
etc...

That is not all! Any combination of any multiple of 187 and "odd" multiples of 187 will also have GCF of 187. 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 187.

374 & 561
374 & 935
748 & 935
748 & 1309
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 187. The lists we created can go on forever.
