A number to be a prime number should follow the criteria, which is that it should not have factors more than 2. Here, 176 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:

 

  1. Counting Divisors Method
  2. Divisibility Test
  3. Prime Number Chart
  4. Prime Factorization

Using the Counting Divisors Method

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


The counting divisors method for 176 would simply be:


Divisors of 176 = 1, 2, 4, 8, 22, 44, 88, 176
Number of divisors = 8


The number 176 can be considered composite.

Professor Greenline from BrightChamps

Using the Divisibility 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 176 are 1, 2, 4, 8, 22, 44, 88, and 176.


Thus, 176 consists of 8 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 are;
2, 3, 5, 7, 11, 13, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.


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

Professor Greenline from BrightChamps

Using the Prime Factorization

This method is only used for a non-prime number/composite number. Since 176 is a composite number, the prime factorization for 176 is:


Factors of 176 = 2 × 2 × 2 × 2 × 11
