97. Nearest square = 10*10 > 97.
Check if 97 is divisible by prime numbers less than 10. i.e.., 2, 3, 5, 7.
If it is not divisible the given number is a prime number.
Similarly for other numbers.

33/3 = 11.
81/9 = 9.
93/3 = 31.
But 97/? not have perfect division number.
97/97 = 1.
81/9 = 9.
93/3 = 31.

97/97 = 1.
