What two numbers have a GCF of 22?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 22.

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 22. Below is the beginning list of multiples of 22 (1 through 7) in numerical order.

1. 22
2. 44
3. 66
4. 88
5. 110
6. 132
7. 154
etc...

Two numbers that have a GCF of 22 can be 22 and any other number on the list above. Thus, two numbers that have a GCF of 22 are:

22 & 44
22 & 66
22 & 88
etc...

That is not all! Any combination of any multiple of 22 and "odd" multiples of 22 will also have GCF of 22. 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 22.

44 & 66
44 & 110
88 & 110
88 & 154
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 22. The lists we created can go on forever.
