What two numbers have a GCF of 14?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 14.

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 14. Below is the beginning list of multiples of 14 (1 through 7) in numerical order.

1. 14
2. 28
3. 42
4. 56
5. 70
6. 84
7. 98
etc...

Two numbers that have a GCF of 14 can be 14 and any other number on the list above. Thus, two numbers that have a GCF of 14 are:

14 & 28
14 & 42
14 & 56
etc...

That is not all! Any combination of any multiple of 14 and "odd" multiples of 14 will also have GCF of 14. 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 14.

28 & 42
28 & 70
56 & 70
56 & 98
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 14. The lists we created can go on forever.
