What two numbers have a GCF of 450?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 450.

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 450. Below is the beginning list of multiples of 450 (1 through 7) in numerical order.

1. 450
2. 900
3. 1350
4. 1800
5. 2250
6. 2700
7. 3150
etc...

Two numbers that have a GCF of 450 can be 450 and any other number on the list above. Thus, two numbers that have a GCF of 450 are:

450 & 900
450 & 1350
450 & 1800
etc...

That is not all! Any combination of any multiple of 450 and "odd" multiples of 450 will also have GCF of 450. 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 450.

900 & 1350
900 & 2250
1800 & 2250
1800 & 3150
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 450. The lists we created can go on forever.
