Write a JavaScript Program to Find the Factors of a Number

As a JavaScript programmer, it’s important to know how to find the factors of a number.

Factors are the numbers that can be multiplied together to get the original number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12.

To find the factors of a number in JavaScript, we can use a simple loop and check each number from 1 to the number itself.

If the number is divisible by the current iteration, then we can add it to the list of factors.

Here’s a JavaScript program that finds the factors of a given number:

function findFactors(num) {
  let factors = [];

  for (let i = 1; i <= num; i++) {
    if (num % i === 0) {
      factors.push(i);
    }
  }

  return factors;
}

// Example usage:
console.log(findFactors(12)); // Output: [1, 2, 3, 4, 6, 12]

In the above code, we define a function findFactors that takes in a number num as its argument. We initialize an empty array factors that we will use to store the factors.

Next, we use a for loop to iterate from 1 to num. We check if num is divisible by the current iteration using the modulus operator (%).

If the remainder is 0, then we know that the current iteration is a factor of num, so we add it to the factors array using the push() method.

Finally, we return the factors array containing all the factors of the given number.

In conclusion, finding the factors of a number is a simple and essential task in JavaScript programming.
