A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. This means it cannot be formed by multiplying two smaller natural numbers. Prime numbers are fundamental in various fields of mathematics and science, acting as the building blocks of the integers. An interesting fact is that the distribution of prime numbers among the natural numbers is still a subject of deep mathematical research, with the famous Prime Number Theorem providing insights into their average distribution.
