Problem
We are required to write a JavaScript function that takes in a number n. Our function should find and return that smallest possible number which is divisible by all numbers from 1 to n.
Example
Following is the code −
const num = 11; const smallestDivisible = (num = 1) => { let res = num * (num - 1) || 1; for (let i = num - 1; i >= 1; i--) { if (res % i) { for (let j = num - 1; j >= 1; j--) { if (!(i % j) && !(res % j)) { res = i * res / j; break; } } } } return res; } console.log(smallestDivisible(num));
Output
27720
