What two numbers have a GCF of 47?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 47.

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 47. Below is the beginning list of multiples of 47 (1 through 7) in numerical order.

1. 47
2. 94
3. 141
4. 188
5. 235
6. 282
7. 329
etc...

Two numbers that have a GCF of 47 can be 47 and any other number on the list above. Thus, two numbers that have a GCF of 47 are:

47 & 94
47 & 141
47 & 188
etc...

That is not all! Any combination of any multiple of 47 and "odd" multiples of 47 will also have GCF of 47. 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 47.

94 & 141
94 & 235
188 & 235
188 & 329
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 47. The lists we created can go on forever.
