# Generating a random number that is divisible by n in JavaScript

We are required to write a JavaScript function that takes in a number as the only argument. The function should then return a random generated number which is always divisible by the number provided by the argument.

## Example

The code for this will be −

const num = 21; // function that generates random numbers divisible by n with a default upper limit of 1000000 const specialRandom = (num = 1, limit = 1000000) => { // getting a random number const random = Math.random() * limit; // rounding it off to be divisible by num const res = Math.round( random / num ) * num; return res; }; console.log(specialRandom(num));

## Output

And the output in the console will be −

6006

This output is likely to differ on each run.
