# Multiples of 3 and 5

###### 30/04/2019

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.

package main

import "fmt"

func main() {
sum := 0
for i := 0; i < 1000; i++ {
if i % 3 == 0 || i % 5 == 0 {
sum += i
}
}
fmt.Print(sum)
}
