We have an ancient Greek mathematician named Eratosthenes to thank for a handy little algorithm for finding the prime numbers in a set. First step: write out all the counting numbers from 2 to the last number in your set: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. Start with 2, that's the first Prime number. Second step: cross all the multiples of 2 (after 2) off your list of numbers. That leaves you with: 2, 3, 5, 7, 9, 11, 13. Next step: the next prime in your list is 3. Cross off all the multiples of 3 the same way. There is only one, 9. Now you are left with: 2, 3, 5, 7, 11, 13. The next prime in your list is 5. There are no multiples of 5 to cross off. Besides, 5 squared is 25 and that's larger than 14, so you know you're done. What's left is a list of the prime numbers less than 14: 2, 3, 5, 7, 11, 13. Congratulations! You've just done "The Sieve of Eratosthenes." It works great for lists of prime numbers all the way up to 50, or 100 or beyond!

### What is the largest composite number but less than 200?

Testing the largest whole number less than 200, 199, we find that it is not evenly divisible by 2, 3, 5, 7, 11 or 13. Since the square root of 199 is between 14 and 15, there's no need to test any prime numbers higher than 14. Therefore, the answer is 198, since it is an even number, and all even numbers are composite numbers because they are divisible by 2. A composite number is the opposite of a prime number.
