### How to check if one number is a multiple of another with JavaScript?

Sometimes, we want to check if one number is a multiple of another with JavaScript.

In this article, we’ll look at how to check if one number is a multiple of another with JavaScript.

### How to check if one number is a multiple of another with JavaScript?

To check if one number is a multiple of another with JavaScript, we can use the `%` operator check if one number divided by the other has a remainder of 0.

For instance, we write:

``````const x = 8
const y = 2
const remainder = x % y;
if (remainder === 0) {
//x is a multiple of y
} else {
//x is not a multiple of y
}
``````

We get the remainder of `x` divided by `y` with the `%` operator and assign the returned remainder to `remainder`.

If `remainder is 0, then `x`is a multiple of`y`.

Otherwise, `x` isn’t a multiple of `y`.

### Conclusion

To check if one number is a multiple of another with JavaScript, we can use the `%` operator check if one number divided by the other has a remainder of 0.
