/* Practice Problem 1

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.
What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

 */

 /* answer = 232,792,560 ...this works but is probably not the best way to do it
 better answer = finding prime factorization of each num and multiplying to get LCM unclear on math*/

    match = false;
while(match === false){
  match = checkMatch(startNum);
  if(match === false){
    startNum++;
  }

/* Practice Problem 2

A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.
Find the largest palindrome made from the product of two 3-digit numbers.
