In 1859, about the zeta function, they described the way that would lead to the demonstration of the theorem of prime numbers. Not all starfish have 5 arms, nor a prime number of arms; for example, it may have nine or ten arms. Within the first case is the Lucas-Lehmer test, developed from 1856. Co-prime numbers are a set of numbers where the common factor among them is 1. A prime number must satisfy three conditions: it must be a natural number (so numbers like 1.2, -7, or √3 are out of the question); it must be greater than 1; 2) Cross off number 1, because all primes are greater than 1. 19 is a prime number. It is a number that is described as a natural number and are greater than (1), since it leads to only be divided between the same and the unit (1), they are based on compound numbers, since they are governed by the division of the same. In 1640; Pierre de Fermat established the small theorem of Fermat, later demonstrated by Leibniz and Euler. The following example takes one input from the console and then checks whether that number is a prime number or not. Additionally, prime numbers are whole numbers that must be greater than one, and as a result, zero and 1 are not considered prime numbers, nor is any number less than zero. This means that a day can be divided into two equal parts of 12 h each, daytime and nighttime. Whereas 14 is not a prime number, as it can be divided by 2 and 7, as well as by 1 and itself.
