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
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 Is 72 a prime or composite number Find out whether a given number is prime or not Check if 72 is a prime number instantly Learn what prime numbers are, how to check primality, and explore faqs on prime numbers.
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 Composite numbers are everything else except 1 and 0
