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.
Answer: 233168
Solution
module.exports = {
answer : () => {
let answer = 0
for (var i = 1; i < 1000; i++) {
if (i % 3 === 0 || i % 5 === 0) {
answer += i;
}
}
return answer;
}
};
