You have a for loop nested in a while loop in order to find prime numbers. The proper way is to set the flag to false before starting the for loop that checks for factors. Inside the for loop, set the flag to true when a factor is found. After the for loop terminates, check the value of the flag. If it is still false, no factors were found and the number is prime.

Setting the flag to false before the for loop and changing it to true when a factor is found allows you to determine if a number is prime by checking the flag's value after the loop. If it remains false, the number is prime.
