## How do you find the greatest common factor in Javascript?

Live Demo:

- function gcd_two_numbers(x, y) {
- if ((typeof x !== ‘number’) || (typeof y !== ‘number’))
- return false;
- x = Math. abs(x);
- y = Math. abs(y);
- while(y) {
- var t = y;
- y = x % y;

**How do you find a common denominator in Javascript?**

Implementation

- let lcm = (n1, n2) => { //Find the gcd first let gcd = gcd(n1, n2); //then calculate the lcm return (n1 * n2) / gcd; } Copy.
- log(lcm(15, 20)); console. log(lcm(5, 7)); Output: 60 35 Copy.
- let lcm = (n1, n2) => { //Find the smallest and biggest number from both the numbers let lar = Math.
- Input: console.

### Have the function division num1 num2 take both parameters being passed and return the greatest common factor?

Have the function Division(num1,num2) take both parameters being passed and return the greatest common factor. That is, return the greatest number that evenly goes into both numbers with no remainder. For example: 12 and 16 both are divisible by 1, 2, and 4 so the output should be 4.

**What is JavaScript closure?**

A closure is the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives you access to an outer function’s scope from an inner function.

#### What is Armstrong number in JavaScript?

According to Wikipedia, an Armstrong number, also called narcissistic number, has the following property: [An Armstrong number] is a number that is the sum of its own digits each raised to the power of the number of digits.

**How do you find the smallest common multiple in Javascript?**

In each iteration,

- The variable min is divided by both the num1 and num2 .
- If both numbers’ remainders are equal to 0, then it is the LCM and the break statement terminates the program.
- If both numbers’ remainders are not equal to 0, the value of min is increased by 1 and the loop continues.

## How do you find the GCD of two numbers?

The steps to calculate the GCD of (a, b) using the LCM method is:

- Step 1: Find the product of a and b.
- Step 2: Find the least common multiple (LCM) of a and b.
- Step 3: Divide the values obtained in Step 1 and Step 2.
- Step 4: The obtained value after division is the greatest common divisor of (a, b).

**How do you find the greatest common denominator in Java?**

Algorithm to Find GCD

- Declare two variables, say x and y.
- Run a loop for x and y from 1 to max of x and y.
- Check that the number divides both (x and y) numbers completely or not. If divides completely store it in a variable.
- Divide the stored number.

### Does Java have built in GCD?

Java BigInteger gcd() method The gcd() method of Java BigInteger class is used to get the greatest common divisor of absolute values of two BigInteger. This method returns a BigInteger whose value is the greatest common divisor of abs (this) and abs (val).

**Is GCD and GCF the same?**

The GCD is sometimes called the greatest common factor (GCF). A very useful property of the GCD is that it can be represented as a sum of the given numbers with integer coefficients.

#### Why do we need JavaScript closures?

In JavaScript, closures are the primary mechanism used to enable data privacy. When you use closures for data privacy, the enclosed variables are only in scope within the containing (outer) function. You can’t get at the data from an outside scope except through the object’s privileged methods.

**What is JavaScript binding?**

JavaScript Function bind() With the bind() method, an object can borrow a method from another object. The example below creates 2 objects (person and member).

## How do you use POW in JavaScript?

pow() function returns the base to the exponent power, as in base^exponent , the base and the exponent are in decimal numeral system. Because pow() is a static method of Math , use it as Math. pow() , rather than as a method of a Math object you created. ( Math has no constructor.)

**How do you check a number is palindrome or not in JavaScript?**

Palindrome Algorithm

- Get the strings or numbers from the user.
- Take a temporary variable that holds the numbers.
- Reverse the given number.
- Compare the original number with the reversed number.
- If the temporary and original number are same, it the number or string is a Palindrome.

### How do you find the smallest common multiple?

How to find LCM by Prime Factorization

- Find all the prime factors of each given number.
- List all the prime numbers found, as many times as they occur most often for any one given number.
- Multiply the list of prime factors together to find the LCM.

**How do you solve GCD problems?**

Finding Greatest Common Divisor by LCM Method

- Step 1: Find the product of a and b.
- Step 2: Find the least common multiple (LCM) of a and b.
- Step 3: Divide the values obtained in Step 1 and Step 2.
- Step 4: The obtained value after division is the greatest common divisor of (a, b).
