# Sum Of Multiples Write a program that, given a number, can 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. Write a program that can find the sum of the multiples of a given set of numbers. To run the tests simply run the command `go test` in the exercise directory. If the test suite contains benchmarks, you can run these with the `-bench` flag: go test -bench .
