What two numbers have a GCF of 395?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 395.

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 395. Below is the beginning list of multiples of 395 (1 through 7) in numerical order.

1. 395
2. 790
3. 1185
4. 1580
5. 1975
6. 2370
7. 2765
etc...

Two numbers that have a GCF of 395 can be 395 and any other number on the list above. Thus, two numbers that have a GCF of 395 are:

395 & 790
395 & 1185
395 & 1580
etc...

That is not all! Any combination of any multiple of 395 and "odd" multiples of 395 will also have GCF of 395. 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 395.

790 & 1185
790 & 1975
1580 & 1975
1580 & 2765
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 395. The lists we created can go on forever.
