Sum Of Multiples

Given a number, find the sum of all the multiples of particular numbers up to but not including that number.

If we list all the natural numbers up to but not including 20 that are multiples of either 3 or 5, we get 3, 5, 6 and 9, 10, 12, 15, and 18.

The sum of these multiples is 78.
