Factor Finder

Factor Finder Project:

A number’s factors are any two other numbers that, when multiplied with each other, produce the number. For example, 2 × 13 = 26, so 2 and 13 are factors of 26. Also, 1 × 26 = 26, so 1 and 26 are also factors of 26. Therefore, we say that 26 has four factors: 1, 2, 13, and 26.  Write a program that takes as input a single integer number, and outputs a complete listing of that number's factors.

When you run the program, the output should look like this:

Enter a number to factor (or "QUIT" to quit):

> 26

1, 2, 13, 26

Enter a number to factor (or "QUIT" to quit):

Enter a number to factor (or "QUIT" to quit):

Enter a number to factor (or "QUIT" to quit):

> quit

Fun fact:  If a number only has two factors (1 and itself), we call that a prime number. Otherwise, we call it a composite number. Use the factor finder to discover some new prime numbers!
