Here is a java code that finds the hcf of three numbers. You can also find the hcf of two numbers with this code.

import java.util.*;

public class HCFOFNumbers {
        public static int hcf(int a, int b) {
                if (b == 0)
                        return a;
                else
                        return hcf(b, a % b);
        }

        public static int hcf(int a, int b, int c) {

                return hcf(hcf(a, b), c);

        }

        public static void main(String[] args) {
                Scanner input = new Scanner(System.in);
                System.out.print("Enter Number 1: ");
                int num1 = input.nextInt();
                System.out.print("Enter Number 2: ");
                int num2 = input.nextInt();
                System.out.print("Enter Number 3: ");
                int num3 = input.nextInt();
                int hcfOfNumbers = HCFOFNumbers.hcf(num1, num2, num3);
                System.out.println("HCF of three numbers " + num1 + "," + num2
                                + " and " + num3 + " is: " + hcfOfNumbers);
        }
}
