If you would like to test code from this task, you may use code from trial division or the Sieve of Eratosthenes. Whether a number is prime (note its name before your code). You may assume that you have a function which determines If your language does not have an isPrime-like function available, Which when all multiplied together, are equal to that number.Įxample 12 = 2 × 2 × 3, so its prime decomposition is greater than 1. The prime decomposition of a number is defined as a list of prime numbers The isPrime variable remains true if the number is a prime number.You are encouraged to solve this task according to the task description, using any language you may know.The isPrime variable is set to false if the number is not a prime number.The isPrime variable is used to store a boolean value: either true or false.If the remainder value is evaluated to 0, that number is not a prime number.The condition number % i = 0 checks if the number is divisible by numbers other than 1 and itself. The for loop is used to iterate through the positive numbers to check if the number entered by the user is divisible by positive numbers ( 2 to user-entered number minus 1). Numbers greater than 1 are tested using a for loop.All negative numbers are excluded because prime numbers are positive.
1 is considered neither prime nor composite.The number entered by the user is checked if it is greater than 1 using if.else if. In the above program, the user is prompted to enter a number. Example: Check Prime Number // program to check if a number is prime or notĬonst number = parseInt(prompt("Enter a positive number: ")) Ĭonsole.log("1 is neither prime nor composite number.") Ĭonsole.log(`$ is a not prime number`) Ĭonsole.log("The number is not a prime number.") For example, 2, 3, 5, 7, 11 are the first few prime numbers. A prime number is a positive integer that is only divisible by 1 and itself.
