Check out example codes for "Java program to find LCM of two numbers". It will help you in understanding the concepts better.

Code Example 1

``````public class LCMOfTwoNumbers
{
public static void main(String[] args)
{
int num1 = 85, num2 = 175, lcm;
lcm = (num1 > num2) ? num1 : num2;
while(true)
{
if(lcm % num1 == 0 && lcm % num2 == 0)
{
System.out.println("LCM of " + num1 + " and " + num2 + " is " + lcm + ".");
break;
}
++lcm;
}
}
}``````

Code Example 2

``````java program to find hcf of two numbers or gcd of two numbers
import java.util.Scanner;
public class HCFOfTwoNumbers
{
public static void main(String[] args)
{
int hcf = 1;
Scanner sc = new Scanner(System.in);
System.out.println("Please enter first number to find gcd or hcf: ");
int number1 = sc.nextInt();
System.out.println("Please enter second number to find gcd or hcf: ");
int number2 = sc.nextInt();
for(int a = 1; a <= number1 && a <= number2; ++a)
{
if(number1 % a == 0 && number2 % a == 0)
hcf = a;
}
System.out.println("HCF of " + number1 + " and " + number2 + " is: " + hcf);
sc.close();
}
}``````

Code Example 3

``````calculate lcm two numbers in java we can use GCD
public class LCMUsingGCD
{
public static void main(String[] args)
{
int num1 = 15, num2 = 25, gcd = 1;
for(int a = 1; a <= num1 && a <= num2; ++a)
{
if(num1 % a == 0 && num2 % a == 0)
{
gcd = a;
}
}
int lcm = (num1 * num2) / gcd;
System.out.println("LCM of " + num1 + " and " + num2 + " is " + lcm + ".");
}
