Perfect Number according to?!

[Salah]

1 is a divisor of any positive natural integer, so there must be considerations for classification of Perfection of a Number.

I mean, there are Four considerations:
1- Perfection according to adding (1) as a divisor. There are 51 numbers discovered until now (12/2020).
2- Perfection according to non-adding of (1) as a divisor. There's no even one Perfect Number according to this consideration. They call the number that satisfy this consideration: Quasiperfect Number.
3- Perfection according to Summation of the Square root of a Square Number two times and not considering the (1).
For example:
Divisors of 4 are: 1,4,2,2
So, the sum of 4 divisors according to this consideration is:
2+2=4,
So, 4 is a Perfect Number according to this consideration.
4- Perfection according to adding (1), and adding The square root of a Square Number two times.
For example:
Sum of divisors of 4=1+2+2=5,
So, 4 is not a Perfect Number according to this consideration.

I think, these considerations are of high importance in:
- Sacred Geometry.
- Sacred Algebra.
- Philosophy of Numbers.
