Question: Prime Factorization. Take your solutions for is prime() and get factors() in the previous problems and create a function that takes an integer as input and returns a list of its prime factors. This process, known as prime factorization, should output a list of factors such that if multiplied together, they will result in the original number. Note that there could be repeats in the list. So if you gave an input of 20, the output would be [2, 2, 5].
