What two numbers have a GCF of 303?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 303.

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 303. Below is the beginning list of multiples of 303 (1 through 7) in numerical order.

1. 303
2. 606
3. 909
4. 1212
5. 1515
6. 1818
7. 2121
etc...

Two numbers that have a GCF of 303 can be 303 and any other number on the list above. Thus, two numbers that have a GCF of 303 are:

303 & 606
303 & 909
303 & 1212
etc...

That is not all! Any combination of any multiple of 303 and "odd" multiples of 303 will also have GCF of 303. 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 303.

606 & 909
606 & 1515
1212 & 1515
1212 & 2121
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 303. The lists we created can go on forever.
