Abundant Number in JAVA

Abundant Number: A number ‘n’ is said to be Abundant Number if sum of all the proper divisors of the number is greater than the number ‘n’.

The difference between Sum & Number is called the abundance.

The abundant number can be called as an excessive number

Example :-

Input                          : 12

Proper Divisors         : 1, 2, 3, 4, 6

Sum of Divisors        : 16

Output                        : It is Abundant Number

Abundance                : 16 – 12 = 4

 

Input                          : 21

Proper Divisors         : 1, 3, 7

Sum of Divisors        : 11

Output                        : It is not Abundant Number

Abundance                : No abundance

Algorithm :-

• Input number

• Store the sum of proper divisors in a variable

• Check if the sum is Greater than the number or not

• If sum is greater than print “It is Abundant Number”

• Also print its abundance by subtracting number from sum.

• Otherwise, Print “It is not an Abundant Number”

• Compile and Run the Program.

Program :-

import java.io.*;

import java.util.*;

class Abundant_Number

{

    public static void main(String args[])

    {

        Scanner in= new Scanner(System.in);

        int n,i,sum=0,x;

        System.out.println("Enter the number");

        n= in.nextInt(); // Enter Number from user

        for(i=1;i<n;i++)

        {

            if(n%i==0)

            {

                sum=sum+i;

            }

        }

        if(sum>n)

        {

            System.out.println("It is Abundant Number : "+n);

            x = sum-n;

            System.out.println("Abundance Number : "+x);

        }

        else

        {

            System.out.println("It is not an Abundant Number : "+n);

        }

    }// end of main

}//end of class
