What two numbers have a GCF of 340?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 340.

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 340. Below is the beginning list of multiples of 340 (1 through 7) in numerical order.

1. 340
2. 680
3. 1020
4. 1360
5. 1700
6. 2040
7. 2380
etc...

Two numbers that have a GCF of 340 can be 340 and any other number on the list above. Thus, two numbers that have a GCF of 340 are:

340 & 680
340 & 1020
340 & 1360
etc...

That is not all! Any combination of any multiple of 340 and "odd" multiples of 340 will also have GCF of 340. 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 340.

680 & 1020
680 & 1700
1360 & 1700
1360 & 2380
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 340. The lists we created can go on forever.
