Indivisible

Indivisible is a term used in mathematics to describe a number that cannot be divided evenly by any other whole number except itself and 1. In other words, an indivisible number (called a prime number) has no divisors other than 1 and itself. For example, 5 is indivisible because only 1 and 5 divide it without leaving a remainder. Prime numbers are fundamental building blocks in mathematics because they can be combined (multiplied) to create many other numbers. The concept of indivisibility helps us understand the structure and relationships between different numbers.
