Question

How to calculate the LCM (Least Common Multiple) of 3 numbers in C#

Answer 1

using System;

class Program
{
    static int getLMC(int a, int b, int c) {
        int lmc = Math.Max(Math.Max(a, b), c);
           
        while(true) {
            if (lmc % a == 0 && lmc % b == 0 && lmc % c == 0) {
                return lmc;
            }
            lmc++;
        }
    }
    static void Main() {
        int a = 12, b = 15, c = 40;
  
        Console.WriteLine("The LCM (Least Common Multiple) is: {0}", getLMC(a, b, c));
    }
}
 
 
 
 
   
/*
run:
   
The LCM (Least Common Multiple) is: 120
   
*/

using System;

class Program
{
    static int getLMC(int a, int b) {
        int lmc = (a > b) ? a : b;
           
        while(true) {
            if (lmc % a == 0 && lmc % b == 0) {
                return lmc;
            }
            lmc++;
        }
    }
    static void Main() {
        int a = 12, b = 15, c = 40;
  
        Console.WriteLine("The LCM (Least Common Multiple) is: {0}", getLMC(getLMC(a, b), c));
    }
}
