A number to be a prime number should follow the criteria that it should not have factors more than 2. Here, 537 has more than 2 factors, hence making it a composite number.

 


Given below are a few ways that can be used to find prime or composite numbers.

 


The different methods we can use to check if a number is a prime number are explained below.

Using the Counting Divisors Method

For the counting divisors method, it is checked whether the number is divisible by any numbers other than 1 and the number itself.


The counting divisors method for 537 would simply be


Divisors of 537 = 1, 3, 9, 59, 177, 537
Number of divisors = 6


The number 537 can be considered composite.

Professor Greenline from BrightChamps

Using the Divisibility Test Method

In the division test, we try to divide the number by any of the prime numbers. If we cannot, then it is considered a prime number.


In the divisibility method, the prime number only has 2 divisors, which are 1 and itself.
The divisors of 537 are 1, 3, 9, 59, 177, and 537.


Thus, 537 consists of 6 factors that divide it completely without any remainder.

Using the Prime Number Chart

The prime number chart is the list of prime numbers starting from 2 to infinity.


The list of prime numbers under 100 is:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.


537 is not present in the list, so it is not a prime number.

Using the Prime Factorization Method

This method is only used for a non-prime number/composite number. Since 537 is a composite number, the prime factorization for 537 is:


Factors of 537 = 3 × 3 × 59
