Numbers that have only 2 factors i.e 1 and the number itself are prime numbers Let’s find out in detail how and why is 72 a prime number? 72, as a composite number, occupies a different position in mathematics compared to prime numbers Unlike a prime number that is divisible only by 1 and itself, 72’s divisibility by multiple numbers illustrates its composite nature. A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers
