Perfect Number

A number is said to be perfect when sum of the positive factors of the number is twice the number.
Example : The positive factors of \( 6 \) are \( 1,2,3,6\)
\( 1 + 2 + 3 + 6 = 2 \cdot 6 \)

There are many perfect numbers such as \( 496, 8128, 33550336 , 8589869056 \) etc.
Find the perfect number between \( 6 \) and \( 496 \).
