Prime numbers, raised to a power, have one more factor than their exponents. The smallest prime number is 2. 210 has eleven factors. 210 = 1024

A beprisque number nnn is an integer which is either one more than a prime number and one less than a perfect square, or one more than a square and one less than a prime. The 5th such number is 10.
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
87 is the only 2-digit number that is 6 greater and 13 less than a square, but it is not prime.

111 is a composite number because it has more than two factors

There is no "the" prime number in that range - there are 21 of them. If you want "the" prime number you will need to be more specific.

1, 2, 3 ,5 , and 7 are all prime numbers less than 10. The lower the number is, the more likely it is to be prime. There is only one number, 2, that is even.
