State if the following is a prime number?
103

A number between 100 and 200 is a prime number if it is not divisible by any prime number less than 15.
Similarly, a number between 200 and 300 is a prime number if it is not divisible by any prime number less than 20.
103 is a prime number because it is not divisible by 2, 3, 5, 7, 11, and 13.
