What two numbers have a GCF of 842?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 842.

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 842. Below is the beginning list of multiples of 842 (1 through 7) in numerical order.

1. 842
2. 1684
3. 2526
4. 3368
5. 4210
6. 5052
7. 5894
etc...

Two numbers that have a GCF of 842 can be 842 and any other number on the list above. Thus, two numbers that have a GCF of 842 are:

842 & 1684
842 & 2526
842 & 3368
etc...

That is not all! Any combination of any multiple of 842 and "odd" multiples of 842 will also have GCF of 842. 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 842.

1684 & 2526
1684 & 4210
3368 & 4210
3368 & 5894
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 842. The lists we created can go on forever.
