What two numbers have a GCF of 73?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 73.

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 73. Below is the beginning list of multiples of 73 (1 through 7) in numerical order.

1. 73
2. 146
3. 219
4. 292
5. 365
6. 438
7. 511
etc...

Two numbers that have a GCF of 73 can be 73 and any other number on the list above. Thus, two numbers that have a GCF of 73 are:

73 & 146
73 & 219
73 & 292
etc...

That is not all! Any combination of any multiple of 73 and "odd" multiples of 73 will also have GCF of 73. 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 73.

146 & 219
146 & 365
292 & 365
292 & 511
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 73. The lists we created can go on forever.
