Display Factors of 3 in Integer

Write a Java method to display the factors of 3 in a given integer.

Pictorial Presentation:

Sample data:
(8) -> 8 = 8
(45) -> 45 = 3 * 3 * 5
(81) -> 81 = 3 * 3 * 3 * 3 * 1

Sample Solution:

Java Code:

import java.util.Scanner;
public class Main { 
 public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Input an integer(positive/negative):");
        int n = in.nextInt();
        System.out.print("\nFactors of 3 of the said integer:\n");
        test(n);
        }

public static void test(int n){
    System.out.print(n + " = ");
    int result = n;
    while (result % 3 == 0){
        System.out.print("3 * ");
        result = result / 3;
    }
    System.out.print(result);
}
}

Sample Output:

Input an integer(positive/negative): 81

Factors of 3 of the said integer:
81 = 3 * 3 * 3 * 3 * 1
