What two numbers have a GCF of 36?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 36.

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 36. Below is the beginning list of multiples of 36 (1 through 7) in numerical order.

1. 36
2. 72
3. 108
4. 144
5. 180
6. 216
7. 252
etc...

Two numbers that have a GCF of 36 can be 36 and any other number on the list above. Thus, two numbers that have a GCF of 36 are:

36 & 72
36 & 108
36 & 144
etc...

That is not all! Any combination of any multiple of 36 and "odd" multiples of 36 will also have GCF of 36. 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 36.

72 & 108
72 & 180
144 & 180
144 & 252
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 36. The lists we created can go on forever.
