What two numbers have a GCF of 693?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 693.

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 693. Below is the beginning list of multiples of 693 (1 through 7) in numerical order.

1. 693
2. 1386
3. 2079
4. 2772
5. 3465
6. 4158
7. 4851
etc...

Two numbers that have a GCF of 693 can be 693 and any other number on the list above. Thus, two numbers that have a GCF of 693 are:

693 & 1386
693 & 2079
693 & 2772
etc...

That is not all! Any combination of any multiple of 693 and "odd" multiples of 693 will also have GCF of 693. 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 693.

1386 & 2079
1386 & 3465
2772 & 3465
2772 & 4851
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 693. The lists we created can go on forever.
