Maximum Product Of Two Primes Less Than N
August 28, 2015
Today we have a fun little exercise based on prime numbers.
Given an integer n > 4, find the maximum product of two prime numbers such that the product is less than n. For instance, when n = 27, the maximum is 2 * 13 = 26, and when n = 50, the maximum is 7 * 7 = 49.
Your task is to write a program to find the maximum product of two primes less than n. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
