What two numbers have a GCF of 195?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 195.

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 195. Below is the beginning list of multiples of 195 (1 through 7) in numerical order.

1. 195
2. 390
3. 585
4. 780
5. 975
6. 1170
7. 1365
etc...

Two numbers that have a GCF of 195 can be 195 and any other number on the list above. Thus, two numbers that have a GCF of 195 are:

195 & 390
195 & 585
195 & 780
etc...

That is not all! Any combination of any multiple of 195 and "odd" multiples of 195 will also have GCF of 195. 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 195.

390 & 585
390 & 975
780 & 975
780 & 1365
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 195. The lists we created can go on forever.
