Let’s take a look at how we can use Python to determine if a number is a prime number. The most naive and straightforward implementation is to loop over the range of numbers from 2 to the number and see if the modulo of the number and the range is equal to 0. If that occurs, then the number has a … See more Prime numbers are a positive integer that’s greater than 1 that also have no other factors except for 1 and the number itself. For example, the number 5 is a prime number, while the number 6 isn’t (since 2 x 3 is equal … See more Now that we’ve developed three functions, we can easily compare the performance of these functions to see the performance gains that we’ll get from them.
