A number is classified as a prime number if it satisfies a certain condition. The number has to be having only two factors 1 and the number itself, all other numbers which have more than two factors are categorized under composite numbers. The prime are used in our everyday life for the security and pin encryption and in machinery building.
A prime number should not have factors more than 2 but 110 has 4 divisors. No, 110 is a composite number.
The divisors of 110 are 1, 2, 5, 10, 11, 22, 55 and 110. Therefore, 110 is a composite number. Composite numbers are the numbers which have factors more than 2.
A number to be a prime number should follow the criteria, which is that it should not have factors more than 2. 110 has factors more than 2, so it is a composite number.
Given below are a few ways that can be used to find prime or composite numbers.
In this method, the divisors of a number are listed, and the number is checked, to be called a prime number. The counting divisors method for 110 would simply be
Divisors of 110 = 1, 2, 5, 10, 11, 22, 55, 110
Number of divisors = 8
The number 110 can be considered composite.
In divisibility method, the prime number only has 2 divisors, which are 1 and itself.
Divisors of 110 = 1, 2, 5, 10, 11, 22, 55, 110
As 110 has factors more than 2 then it is not a prime number.
We write the prime number chart up to 10, which helps in sorting numbers.
The prime numbers from 1 to 150 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, 101, 103, 107, 109, 113, 127, 131, 137, 139, and 149. 110 is not on the list, so it is not a prime number.
This method is only used for a composite number. Since 110 is a composite number, prime factorization for 110 is: 21 × 51 × 111
Hence, the prime factors of 110 are 2, 5, and 11.
