What two numbers have a GCF of 162?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 162.

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 162. Below is the beginning list of multiples of 162 (1 through 7) in numerical order.

1. 162
2. 324
3. 486
4. 648
5. 810
6. 972
7. 1134
etc...

Two numbers that have a GCF of 162 can be 162 and any other number on the list above. Thus, two numbers that have a GCF of 162 are:

162 & 324
162 & 486
162 & 648
etc...

That is not all! Any combination of any multiple of 162 and "odd" multiples of 162 will also have GCF of 162. 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 162.

324 & 486
324 & 810
648 & 810
648 & 1134
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 162. The lists we created can go on forever.
