Project Euler: Problem 5

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

    const solutionFive = () => {
        const oneToTwenty = Array.from({ length: 20 }, (x, i) => i + 1);
        for (let i = 20; i !== 0; i++) {
            if (oneToTwenty.every(num => i % num === 0)) {
                return i;
            }
        }
    };
