A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself. The smallest twenty-five prime numbers (all the 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.
Note: 1 is not a prime number.
Hope this will help you. Have a nice day!

Please take any perfect square near of 97 i.e 10*10=100. Now find all prime numbers which are less than 10 that are 3,5,7.Now at last check wheather 97 is divisible by 2,3,7.If it is divisible then number is not prime else it is prime.
