A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Prime numbers are fundamental in number theory due to their role as the building blocks of the integers, analogous to atoms in chemistry.
Prime numbers are natural numbers greater than 1 that have no divisors other than 1 and themselves, serving as the building blocks of number theory. They play a crucial role in various fields, including cryptography, due to their properties and distribution patterns.
