Hi All

i am doing a few revision questions before i go back to college next week and i think i have done this wrong ( the code i put together finds the factor of the numbered entered ) here is the question and the code i have done so far.

Write a program that will determine whether a number entered has either 3 or 11 as a factor.

// revision practical 6c question 5

// Gman

// 4.11.11



import java.util.Scanner;

	public class NumberFactorEntered

	{

	

		public static void main(String[] args)

		{

			

			

			Scanner kb = new Scanner(System.in);

				// declare variable

			int num1 = 0;

				// get number

			System.out.print("Enter a number : ");

			num1 = kb.nextInt();

				 // calculate number to find the factors

			for ( int i = 1; i <= num1; i++)

			{

					// if number has no remainder than display

				if ( num1 % i == 0 )

				{

				System.out.println(i + " is a Factor of " + num1);

				}

			}

		

		}

	

	}

Why are you not just testing for divisibility by 3 and 11?

Thanks for help WingedPanther so i was going about it wrong..

[WingedPanther]

One thing I've learned, it's much easier to solve a different, but similar problem, than to solve the actual problem :) Happens in math and programming.

very true , thanks again.
