What is a indivisible number?

An indivisible number, also known as a Prime number, is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other Words, it cannot be divided evenly by any other number except for 1 and itself. Examples of indivisible numbers include 2, 3, 5, 7, 11, and so on. These numbers play a fundamental role in number theory and are the building blocks of all natural numbers through the process of prime factorization.
