Why is 1113 not a prime number?

For a number to be a prime number, it should have only 2 factors: 1 and the number itself. Since 1113 has more than 2 factors, it is considered a composite number.


Given below are a few ways that can be used to determine whether a number is prime or composite.


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 itself.


The counting divisors method for 1113 would be:


Divisors of 1113 = 1, 3, 371, 1113
Number of divisors = 4


Since the number 1113 has more than 2 divisors, it is a composite number.

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.


For 1113, the divisors are 1, 3, 371, and 1113.


Thus, 1113 has 4 factors that divide it completely without any remainder, making it a composite number.

Using the Prime Number Chart

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


The list of prime numbers under 100 are:
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.


Since 1113 is not present in the chart and is divisible by other numbers apart from 1 and itself, it is not a prime number.

Using the Prime Factorization

This method is used only for composite numbers. Since 1113 is a composite number, the prime factorization for 1113 is:
Factors of 1113 = 3 × 371
