What two numbers have a GCF of 330?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 330.

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 330. Below is the beginning list of multiples of 330 (1 through 7) in numerical order.

1. 330
2. 660
3. 990
4. 1320
5. 1650
6. 1980
7. 2310
etc...

Two numbers that have a GCF of 330 can be 330 and any other number on the list above. Thus, two numbers that have a GCF of 330 are:

330 & 660
330 & 990
330 & 1320
etc...

That is not all! Any combination of any multiple of 330 and "odd" multiples of 330 will also have GCF of 330. 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 330.

660 & 990
660 & 1650
1320 & 1650
1320 & 2310
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 330. The lists we created can go on forever.
