6443 = 6482 = 64
The smallest perfect square is 121.
So far, no odd perfect numbers have been found to exist. If and only if one does exist, it will be far larger than the number in the question. In fact, it has been proven concretely that if an odd perfect number exists, it is greater than 10^300, and it is conjectured that if such a number exists, it is greater than 10^500.
463 is a whole number. So there's no different whole numberthat's any closer to it than it already is.

The first perfect square which is greater than 300 is 324.
There is no such number as "the smallest decimal".Any number you give me, no matter how small, I can always give you back a different numberthat's smaller than yours.

A perfect number equals the sum of its proper divisors. A deficient number is greater than the sum of its proper divisors. An abundant number is less than the sum of its proper divisors. Proper divisors of a number do not include the number itself.
Abundant is a number for which the sum of all its proper factors is greater than the number itself. Deficient is a number for which the sum of all its proper factors is less than the number itself. Perfect is a number for which the sum of all its proper factors is the number itself.
Find the sum of the proper divisors of that number.a perfect number equals the sum of its proper divisorsa deficient number is greater than the sum of its proper divisorsan abundant number is less than the sum of its proper divisors
