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!

To find prime no we have to divide the number with 2, 3 & 7.
Then only is it called as a prime number.

3 * 11 = 33,
3 * 3 * 9 = 81,
3 * 31 = 93,
But 97/3 = It's not whole number. So 97 is the correct answer.

If a number have exactly two factors that number called prime number.
ex:7 has 1 and 7 only factors so its prime number and suppose 6 has 1,2,3,6 has factors so it's not the prime number.because it should be exactly 2 factors but here 4 factors are theirs. So it's not the prime number.
Hope you, understand
