Chapter 15, Problem 15.24E

(Sieve of Eratosthenes) Modify Exercise 15.23, the Sieve of Eratosthenes, so that, if the number the user inputs into the program is not prime, the program displays the prime factors of the number. Remember that a prime number’s factors are only 1 and the prime number itself. Even- nonprime number has a unique prime factorization. For example, the factors of 54 are 2, 3, 3 and 3. When these values are multiplied together, the result is 54. For the number 54, the prime factors output should be 2 and 3.
