Factors of a Number Program in java

In this post, we will learn Factors of a Number Program in java Programming language.

Question:

Betsy  teaches her daughter to find the factors of a given number.  When she provides a number to her daughter, she should tell the factors of that number.  Help her to do this, by writing a program.

Write a class FindFactor.java and write the main method in it.

Note : 

• If the input provided is negative, ignore the sign and provide the output. If the input is zero
• If the input is zero the output should be “No Factors”.

Sample Input 1 :

54

Sample Output 1 :

1, 2, 3, 6, 9, 18, 27, 54

Sample Input 2 :

-1869

Sample Output 2 :

1, 3, 7, 21, 89, 267, 623, 1869

CODE:–

import java.util.*;
import java.lang.*;
public class FindFactor
{
    public static void main (String[] args) {
        Scanner sc = new Scanner(System.in);
        int num=Math.abs(sc.nextInt());
        if(num==0)
        {
            System.out.println("No Factors");
        }
        else
        {System.out.print("1");
            for(int i=2;i<=num;i++)
            {
                if(num%i==0)
                {
                    System.out.print(", "+i);
                }
            }
        }
    }
}
