What two numbers have a GCF of 3030?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 3030.

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 3030. Below is the beginning list of multiples of 3030 (1 through 7) in numerical order.

1. 3030
2. 6060
3. 9090
4. 12120
5. 15150
6. 18180
7. 21210
etc...

Two numbers that have a GCF of 3030 can be 3030 and any other number on the list above. Thus, two numbers that have a GCF of 3030 are:

3030 & 6060
3030 & 9090
3030 & 12120
etc...

That is not all! Any combination of any multiple of 3030 and "odd" multiples of 3030 will also have GCF of 3030. 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 3030.

6060 & 9090
6060 & 15150
12120 & 15150
12120 & 21210
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 3030. The lists we created can go on forever.
