What two numbers have a GCF of 1340?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1340.

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 1340. Below is the beginning list of multiples of 1340 (1 through 7) in numerical order.

1. 1340
2. 2680
3. 4020
4. 5360
5. 6700
6. 8040
7. 9380
etc...

Two numbers that have a GCF of 1340 can be 1340 and any other number on the list above. Thus, two numbers that have a GCF of 1340 are:

1340 & 2680
1340 & 4020
1340 & 5360
etc...

That is not all! Any combination of any multiple of 1340 and "odd" multiples of 1340 will also have GCF of 1340. 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 1340.

2680 & 4020
2680 & 6700
5360 & 6700
5360 & 9380
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1340. The lists we created can go on forever.
