Can I get help implementing this function in LISP please? Thanks!

Given a positive integer n, return a list of its prime factors, in increasing order. Include the correct number of occurrences, e.g prime_factors(24) 1S [2,2,2,3 *Homework3> primeFactors 5 Homework3> primeFactors 50 [2,5,51 *Homework3> primeFactors 66 *Homework3> primeFactors 463 [ 463] *Homework3> primeFactors 512 [2,2,2,2,2,2,2,2,2] Given a positive integer n, return a list of its prime factors, in increasing order.
