What two numbers have a GCF of 142?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 142.

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 142. Below is the beginning list of multiples of 142 (1 through 7) in numerical order.

1. 142
2. 284
3. 426
4. 568
5. 710
6. 852
7. 994
etc...

Two numbers that have a GCF of 142 can be 142 and any other number on the list above. Thus, two numbers that have a GCF of 142 are:

142 & 284
142 & 426
142 & 568
etc...

That is not all! Any combination of any multiple of 142 and "odd" multiples of 142 will also have GCF of 142. 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 142.

284 & 426
284 & 710
568 & 710
568 & 994
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 142. The lists we created can go on forever.
