**An example**
To start with, here are two versions of a short Groovy program that solves the first problem of

Project Euler :

*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. Find the sum of all the multiples of 3 or 5 below 1000.*
Both would be called using

*println getSumOfMultiples([3,5], 1000)*
