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 We do not consider 72 as a prime number, because it can be written as a product of two smaller natural numbers (check the factors of number 72 below). 72 is a multiple of 2 72 is a multiple of 3 72 is a multiple of 4 72 is a multiple of 6 72 is a multiple of 8 72 is a multiple of 9 72 is a multiple of 12 72 is a multiple of 18 72 is a multiple of 24 72 is a multiple of 36 for 72 to be a prime number, it would have been required that 72 has only two divisors, i.e., itself and 1

A math tutor would explain that prime numbers can only be divided by 1 and themselves
In this thinkster article, let’s determine whether 72 is a prime or composite number by analyzing it from different angles. 72 is a composite number Composite numbers are numbers that have more than two factors The number 72 is divisible by 2 other than 1 and itself, so it meets the definition of a composite number
Facts about composite numbers fact 1 Every natural number greater than 1 is either prime or composite 4 is the smallest composite number. The prime factorization of 72 = 2 3 •3 2 the number 72 is not a prime number because it is possible to factorize it
In other words, 72 can be divided by 1, by itself and at least by 2 y 3
This is a so called 'composite number'. A prime number has only 2 factors which are 1 and itself
