Greatest Number Divisible by N Within a Bound in JavaScript

Problem

We are required to write a JavaScript function that takes in a number n and bound number b.

Our function should find the largest integer num, such that −

• num is divisible by divisor

• num is less than or equal to bound

• num is greater than 0.

Example

Following is the code −

 Live Demo

const n = 14;
const b = 400;
const biggestDivisible = (n, b) => {
   let max = 0;
   for(let j = n; j <= b; j++){
      if(j % n == 0 && j > max){
         max = j;
      };
   }
   return max;
};
console.log(biggestDivisible(n, b));
