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.
function sumOfMultiples(x, y, z) {
let sum = 0;
for (let i = 1; i * x < z; i++) {
sum += x * i;
}
for (let i = 1; i * y < z; i++) {
sum += y * i;
}
for (let i = 1; i * (x * y) < z; i++) {
sum -= (x * y) * i;
}
console.log(sum);
}
sumOfMultiples(3, 5, 1000);
