Find out the divisors or the factors of any number using java program

Program to display the Factors of any number

“Factors” are the numbers you multiply to get another number. For instance, factors of 20 are 4 and 5, because 4×5 = 20. Some numbers have more than one factorization (more than one way of being factored). For instance, 10 can be factored as 1×10, or 2×5.

For Example:-

The factors of 100

Answer : 1,2,4,5,10,20,25,50,100.

import java.util.Scanner; //Calling Scanner Class public class Divisors

{     

// instance variable    

 private int x;    

 public void calculation() //Non return type, Non Parameterized method    

{         

System.out.println(“Enter any number”); //Instruction to user  

x= new Scanner(System.in).nextInt(); //Getting input         

System.out.println(“The divisors of “+x+” are:”); //Output        

 int a=1; //Declaring and initializing the variable         

while(a<=x) //Loop the program until a is less than or equals to x        

{            

if(x%a==0) //Conditon            

{                 

System.out.println(a); //Output          

}          

  a++; //Using Increment Operator      

}    

}     

public static void main(String []args) //Main method    

{         

Divisors d= new Divisors(); //Creating object of Divisors class

d.calculation(); //Calling method    

}

}

Output:-

If you have any problem regards Increment operator then, this site will definitely help to know well about it.

If you need some data from the user then you need to import the Scanner class. If you want to know more about Scanner class then, please visit this link (https://programmerbrothers.blogspot.com/2019/04/scanner-class-in-java-scanner-is-class.html)
