JavaScript: Divide an integer by another integer as long as the result is an integer and return the result

JavaScript Basic: Exercise-106 with Solution

Write a JavaScript program to divide an integer by another integer as long as the result is an integer and return the result.

Sample Solution:

JavaScript Code:

// Function to divide a number by a digit
function divide_digit(num, d) {
    // Check if divisor is 1, return the number itself
    if (d == 1)
        return num;
    else {
        // Loop to divide the number by the divisor until not divisible
        while (num % d === 0) {
            num /= d; // Divide the number by the divisor
        }
        return num; // Return the final divided number
    }
}

// Example usage of the function with different numbers and divisors
console.log(divide_digit(-12, 2)); // Output: -3
console.log(divide_digit(13, 2)); // Output: 13
console.log(divide_digit(13, 1)); // Output: 13 

Output:

-3
13
13

ES6 Version:

// Function to divide a number by a divisor until it's not divisible anymore
const divide_digit = (num, d) => {
    if (d === 1) // If the divisor is 1, return the number as it is
        return num;
    else {
        while (num % d === 0) { // Loop while the number is divisible by the divisor
            num /= d; // Divide the number by the divisor
        }
        return num; // Return the resulting number after division
    }
};

// Example usage of the function
console.log(divide_digit(-12, 2)); // Output: -3 (divided -12 by 2 until it's not divisible)
console.log(divide_digit(13, 2)); // Output: 13 (13 is not divisible by 2)
console.log(divide_digit(13, 1)); // Output: 13 (divisor is 1, returns the number as it is)
