#Prime Numbers
#Instructions
#Prime numbers are numbers that can only be cleanly divided by itself and 1.

#https://en.wikipedia.org/wiki/Prime_number

#You need to write a function that checks whether if the number passed into it is a prime number or not.

#e.g. 2 is a prime number because it's only divisible by 1 and 2.

#But 4 is not a prime number because you can divide it by 1, 2 or 4.
