Python Program to Check Prime Number - GeeksforGeeks
Webb23 sep. 2024 · How it works: To check for a prime number we successively divide a number n from 2 to n-1. If n is not divisible by any number between this range then it is a prime number. Example 1: Is 5 a prime number? Hence, 5 is a prime number. Example 2: Is 6 a prime number Number 6 is divisible by 2. Hence, it is not a prime number. WebbFew prime number are − 1, 2, 3, 5 , 7, 11 etc. Algorithm Algorithm of this program is very easy − START Step 1 → Take integer variable A Step 2 → Divide the variable A with (A-1 … how did they vote congress
