Rule 1: Divisibility Check:

Prime numbers are natural numbers that are greater than 1 and have no divisors other than 1 and the number itself. In the divisibility check rule, we check whether the number is divisible by 2, 3, 5, or 7. If it's divisible by any of these numbers, then it's not a prime number.

Rule 2: Prime Factorization:

In this method, we break down all the numbers into their prime factors, showing them as the product of prime numbers.

Rule 3: Sieve of Eratosthenes Method:

The sieve of Eratosthenes is an ancient algorithm used to find all prime numbers up to a given limit. First, list all numbers from 1 to 110. Then start with the first prime number, 2. Mark all multiples of 2 as non-prime. Repeat the process for the next unmarked prime number and continue until you reach the square root of 110, approximately 10.48. The remaining unmarked numbers are the prime numbers.

Tips and Tricks for Prime Numbers 1 to 110

Use common shortcuts to memorize the prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.

Use these numbers as references.

Practice using the method of Sieve of Eratosthenes efficiently.

Numbers like 4, 8, 9, 16, 25, and 36 are never prime.

Knowing the common powers of numbers helps in avoiding unnecessary checks.
