Given a positive integer n, implement a function that finds the smallest number that is evenly divisible by the integers 1 through n inclusive. Return value as a string.
Smallest(1) ➞ "1"
Smallest(5) ➞ "60"
Smallest(10) ➞ "2520"
Smallest(20) ➞ "232792560"You will need to cope with numbers larger than Int64.MaxValue (see Resources).
