Hi Friends 👋,

Welcome To Infinitbility! ❤️

To check if a number is divisible by another number, use the remainder ( % ) operator if get `0` means the number is divisible else not.

Note: Here, another number is any number like 3, 4, 5, 6, 7, 8, etc.

Today, I’m going to show How do I check if a number is divisible by another number in javascript, here I will use the modulo ( % ) operator and `if... else` statements to check if a number is divisible by another number or not.

Let’s start the today’s tutorial How do you check if a number is divisible by another number in javascript?

In the following example, we are going to do the number is a divisible 3 or not.

If the input number is divisible by `3` we will log `input number divisible` else `input number not divisible`.

let’s write the code.

``````const inputNum = 15;

if (inputNum % 3 == 0) {
console.log('✅ input number divisible');
} else {
console.log('⛔️ input number not divisible');
}
``````

In the above program, we have use `15` as input number, after that we check it’s divisible by `3` or not.

let’s check the output.
