What two numbers have a GCF of 856?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 856.

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 856. Below is the beginning list of multiples of 856 (1 through 7) in numerical order.

1. 856
2. 1712
3. 2568
4. 3424
5. 4280
6. 5136
7. 5992
etc...

Two numbers that have a GCF of 856 can be 856 and any other number on the list above. Thus, two numbers that have a GCF of 856 are:

856 & 1712
856 & 2568
856 & 3424
etc...

That is not all! Any combination of any multiple of 856 and "odd" multiples of 856 will also have GCF of 856. 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 856.

1712 & 2568
1712 & 4280
3424 & 4280
3424 & 5992
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 856. The lists we created can go on forever.
