What two numbers have a GCF of 2142?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2142.

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 2142. Below is the beginning list of multiples of 2142 (1 through 7) in numerical order.

1. 2142
2. 4284
3. 6426
4. 8568
5. 10710
6. 12852
7. 14994
etc...

Two numbers that have a GCF of 2142 can be 2142 and any other number on the list above. Thus, two numbers that have a GCF of 2142 are:

2142 & 4284
2142 & 6426
2142 & 8568
etc...

That is not all! Any combination of any multiple of 2142 and "odd" multiples of 2142 will also have GCF of 2142. 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 2142.

4284 & 6426
4284 & 10710
8568 & 10710
8568 & 14994
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 2142. The lists we created can go on forever.
