The last digit of 200 is 0, so it is divisible by 5 and is therefore not prime.įor 200 to be a prime number, it would have been required that 200 has only two divisors, i.e., itself and 1. The list of all positive divisors (i.e., the list of all integers that divide 200) is as follows: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200.įor 200 to be a prime number, it would have been required that 200 has only two divisors, i.e., itself and 1.Īctually, one can immediately see that 200 cannot be prime, because 5 is one of its divisors: indeed, a number ending with 0 or 5 has necessarily 5 among its divisors. It is possible to find out using mathematical methods whether a given integer is a prime number or not.įor 200, the answer is: No, 200 is not a prime number.
