A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, a prime number is a whole number greater than 1 that cannot be formed by multiplying two smaller whole numbers. For example, 2, 3, 5, 7, 11, and 13 are prime numbers because they cannot be divided evenly by any other number except 1 and themselves. Prime numbers play a fundamental role in number theory and have various applications in mathematics and computer science, such as in cryptography and prime factorization algorithms.

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, a prime number is a whole number greater than 1 that cannot be formed by multiplying two smaller whole numbers. For example, 2, 3, 5, 7, 11, and 13 are prime numbers because they cannot be divided evenly by any other number except 1 and themselves. Prime numbers play a fundamental role in number theory and have various applications in mathematics and computer science, such as in cryptography and prime factorization algorithms.
Solution
Un número primo es un número natural mayor que 1 que no tiene divisores positivos aparte de 1 y él mismo. En otras palabras, un número primo es un número entero mayor que 1 que no puede formarse multiplicando dos números enteros más pequeños. Por ejemplo, 2, 3, 5, 7, 11 y 13 son números primos porque no pueden dividirse de manera uniforme por ningún otro número excepto 1 y ellos mismos. Los números primos juegan un papel fundamental en la teoría de números y tienen varias aplicaciones en matemáticas y ciencias de la computación, como en criptografía y algoritmos de factorización prima.
