Smallest multiple

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?

export const findSmallestMultiple = () => {

const divisors = [

20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2

]

let num = 21

let result

while (!result) {

const isDivisibleByAll = divisors.every((divisor) => num % divisor === 0)

if (isDivisibleByAll) result = num

else num++

}

return result

}
