What two numbers have a GCF of 153?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 153.

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 153. Below is the beginning list of multiples of 153 (1 through 7) in numerical order.

1. 153
2. 306
3. 459
4. 612
5. 765
6. 918
7. 1071
etc...

Two numbers that have a GCF of 153 can be 153 and any other number on the list above. Thus, two numbers that have a GCF of 153 are:

153 & 306
153 & 459
153 & 612
etc...

That is not all! Any combination of any multiple of 153 and "odd" multiples of 153 will also have GCF of 153. 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 153.

306 & 459
306 & 765
612 & 765
612 & 1071
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 153. The lists we created can go on forever.
