hi friends, im a newbie at C,

im trying to code for a program which cud return all prime numbers in a specific range.

its returning the results with an error, which is , it also includes the products of two prime numbers in results,
for example 15=3*5 and 21=3*7

my code is
---------------------------------------------------------

#include<conio.h>
#include<stdio.h>
void main()
{
clrscr();
for (int i=1;i<=300;i++)
 {
  for(int j=2;j<=i;j++)
   if(i%j==0 )

   break;
   else
       {
	printf("\t%d ",i);
	break;
	}
  }
getche();
}

--------------------------------------------------
Result:

3 5 7 9 11 13 15 17 19 21 23 .................

kindly guide me where the problem resides.
which is letting 15,21 etc in output.
