# JavaScript Program to Find the Factors of a Number

#### In this example, you will learn to write a JavaScript program that finds all the factors of an integer.

To be the factors of a number, the factor number should exactly divide the number (with **0** remainder). For example,

The factor of **12** is **1**, **2**, **3**, **4**, **6**, and **12**.

## Example: Factors of Positive Number

```
// program to find the factors of an integer
// take input
let num = prompt('Enter a positive number: ');
console.log(`The factors of ${num} is:`);
// looping through 1 to num
for(let i = 1; i <= num; i++) {
// check if number is a factor
if(num % i == 0) {
console.log(i);
}
}
```

**Output**

Enter a positive number: 12 The factors of 12 is: 1 2 3 4 6 12

In the above program, the user is prompted to enter a positive integer.

- The
`for`

loop is used to loop through**1**to the number entered by the user. - The modulus operator
`%`

is used to check if`num`is exactly divisible. - In each iteration, a condition is checked if
`num`is exactly divisible by`i`. -
`if(num % i == 0)`

- If the above condition is met, the number is displayed.
