Find divisors of a number java: In the previous article, we have seen Java Program to Check if All the Digits of a Number are in Decreasing Order

In this article we are going to count total numbers of divisors of a number in java.

Java Program to Count Total Number of Divisors of a Number

Approach:

  • Ask the user to enter the number and store it
  • Run a for loop from 1 to the entered number and count the numbers that leave a remainder of 0.
  • Print the count/result.
import java.util.*;
public class Main 
{
    public static void main(String[] args)
    {
        // Class to take input
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter a number to check - ");
        // Taking inout from user
        int num = scan.nextInt();
        int count=0;
        // Loop to count the number of divisors
        for(int i = 1; i<= num;i ++)
        {
            // Increments count if the number is divisible by i
            if(num%i==0)
                count++;
        }
        // Prints the result
        System.out.print(num+" has "+count+" divisors.");

    }
}
Output:

Enter a number to check - 54
54 has 8 divisors.
