Question

write a program in java to find factors of a number entered by user

Answer 1

import java.util.Scanner;

public class Factor{

public static void main(Stirng..args){

Scanner sc=new Scanner(System.in);

int a=sc.nextInt();

System.out.println("The factor of :"+a+" is");

for(int i=1;i<=a;i++){

if(a%i==0){

System.out.println(i+" ");

}

}

}

}

Answer 2

Hope it helps ^_^

I have also added all the possible outputs

import java.util.Scanner;

public class FactorTeller{

   public static void main(String [] args){

       Scanner sc = new Scanner(System.in);

       int i, num;

       System.out.print("Enter a number in order to know its factors: ");

       num = sc.nextInt();

       System.out.println("The factors of the given number are as follows: ");

       for (i = 1; i <= num; i++){

           if(num % i == 0){

               System.out.println(i);  

           }

       }

   }

}

Outputs:

Enter a number in order to know its factors: 20

The factors of the given number are as follows:  

1

2

4

5

10

20
