Sum of Multiples

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Write a program that, given a number, can find the sum of all the multiples of 3 or 5 up to and including that number.

Allow the program to be configured to find the sum of multiples of numbers other than 3 and 5.
