## How do you find the LCM of two numbers in Java?

Algorithm

1. Initialize A and B with positive integers.
2. Store maximum of A & B to the max.
3. Check if max is divisible by A and B.
4. If divisible, Display max as LCM.
5. If not divisible then step increase max, go to step 3.

### How do you find the LCM of two numbers in Java using for loops?

JAVA program to find lcm of two numbers

1. Logic. We first find the maximum between the two numbers as we will use a for loop to iterate till we reach the maximum value out of both the nos which is divisble by both the numbers.
2. Dry Run of the Program. Take input ‘a’ ‘b’ .
3. Program.
4. Output.

How do you write a LCM program in Java?

LcmExample4.java

1. import java.util.Scanner;
2. public class LcmExample4.
3. {
4. public static void main(String args[])
5. {
6. Scanner sc = new Scanner(System.in);
7. System.out.print(“Enter the first number: “);
8. int x = sc.nextInt();

How do you find the LCM and GCD of two numbers in Java?

Java Program to Find the GCD and LCM of two Numbers

1. //This is sample program to calculate the GCD and LCM of two given numbers.
2. import java.util.Scanner;
3. public class GCD_LCM.
4. {
5. static int gcd(int x, int y)
6. {
7. int r=0, a, b;
8. a = (x > y) ? x : y; // a is greater number.

## What is the LCM of two numbers?

LCM (Least Common Multiple) of two numbers is the smallest number which can be divided by both numbers. For example, LCM of 15 and 20 is 60, and LCM of 5 and 7 is 35.

### What is the HCF of 2 and 2?

The GCF of 2 and 2 is 2.

What is the HCF of 2 and 4?

HCF of 2 and 4 by Prime Factorization As visible, 2 and 4 have only one common prime factor i.e. 2. Hence, the HCF of 2 and 4 is 2.

How to find the LCM of two numbers?

We can also use GCD to find the LCM of two numbers using the following formula: LCM = (n1 * n2) / GCD. If you don’t know how to calculate GCD in Java, check Java Program to find GCD of two numbers. Example 2: Calculate LCM using GCD

## Which is the least common multiple of two numbers in Java?

LCM of Two Numbers in Java In arithmetic, the Least Common Multiple (LCM) of two or more numbers is the least positive number that can be divided by both the numbers, without leaving the remainder. It is also known as Lowest Common Multiple (LCM), Least Common Denominator, and Smallest Common Multiple.

### What is the relation between GCD and LCM?

There’s an interesting relation between the LCM and GCD (Greatest Common Divisor) of two numbers that says that the absolute value of the product of two numbers is equal to the product of their GCD and LCM. As stated, gcd (a, b) * lcm (a, b) = |a * b|.

What is the LCM of 72 and 120?

The LCM of two integers is the smallest positive integer that is perfectly divisible by both the numbers (without a remainder). The LCM of 72 and 120 is 360. In this program, the two numbers whose LCM is to be found are stored in variables n1 and n2 respectively.

How do you find the LCM of two numbers in Java? Algorithm Initialize A and B with positive integers. Store maximum of A & B to the max. Check if max is divisible by A and B. If divisible, Display max as LCM. If not divisible then step increase max, go to step 3. How…
