Is this supposed to make sense?

"I’m number is called a perfect number if a equals the sum of all of its fantastic"

In the second line, do you mean "for instance"?

What is this? " because it matters"
Wow, what garbled language !!

Fortunately, I am guessing you are talking about perfect numbers.
As far back as Euclid it was know that if
if p is prime, then 2^p - 1 is a prime number, then
(2^p -1)(2^(p-1) ) is a perfect number.

e.g.
p = 2 ---->(2^2 - 1)(2^(2-1)) = 3(2) = 6 <-- your given
p = 3 --->(2^3 - 1)(2^(3-1) = 7(4) = 28
check: 1+2+4+7+14 = 28 <---- answer to your question

p = 5 ---> (2^5 - 1)(2^(5-1)) = 31(16) = 496

for fun , find the next one

btw, the ancient Greeks called numbers abundant, if the sum of the factors exceeded the number, and they called it deficient if the sum of the factors was less than the number itself.
No extra charge for the extra history lesson.
I wonder if Bruce will come back to see your knowledgeable answer and extra history lesson, Reiny.
