No, because the number 143 has four factors 1, 11, 13, and 143. Hence, 143 is not a prime number it is therefore a composite number. In thismathsarticle, we shall check whether 143 is a prime number or a composite number. We will also find the prime factorization of 143 and also ...
the simpliest way to check if 'n' is prime is something like this: bool Prime(int n) { for (int i= 2; i<= Math.Sqrt(n); i++) { if (n%i == 0) return false; } return true; } This methode returns true if 'n' is prime and false otherwise. This algorithm s...
