What two numbers have a GCF of 622?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 622.

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 622. Below is the beginning list of multiples of 622 (1 through 7) in numerical order.

1. 622
2. 1244
3. 1866
4. 2488
5. 3110
6. 3732
7. 4354
etc...

Two numbers that have a GCF of 622 can be 622 and any other number on the list above. Thus, two numbers that have a GCF of 622 are:

622 & 1244
622 & 1866
622 & 2488
etc...

That is not all! Any combination of any multiple of 622 and "odd" multiples of 622 will also have GCF of 622. 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 622.

1244 & 1866
1244 & 3110
2488 & 3110
2488 & 4354
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 622. The lists we created can go on forever.
