What two numbers have a GCF of 48?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 48.

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 48. Below is the beginning list of multiples of 48 (1 through 7) in numerical order.

1. 48
2. 96
3. 144
4. 192
5. 240
6. 288
7. 336
etc...

Two numbers that have a GCF of 48 can be 48 and any other number on the list above. Thus, two numbers that have a GCF of 48 are:

48 & 96
48 & 144
48 & 192
etc...

That is not all! Any combination of any multiple of 48 and "odd" multiples of 48 will also have GCF of 48. 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 48.

96 & 144
96 & 240
192 & 240
192 & 336
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 48. The lists we created can go on forever.
