What two numbers have a GCF of 605?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 605.

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 605. Below is the beginning list of multiples of 605 (1 through 7) in numerical order.

1. 605
2. 1210
3. 1815
4. 2420
5. 3025
6. 3630
7. 4235
etc...

Two numbers that have a GCF of 605 can be 605 and any other number on the list above. Thus, two numbers that have a GCF of 605 are:

605 & 1210
605 & 1815
605 & 2420
etc...

That is not all! Any combination of any multiple of 605 and "odd" multiples of 605 will also have GCF of 605. 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 605.

1210 & 1815
1210 & 3025
2420 & 3025
2420 & 4235
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 605. The lists we created can go on forever.
