A number is perfect if the sum of factors of the number below it is same as that number.
for example
6= 1+2 + 3
28 = 1+2 + 4+7+14
496 = 1+2+4+8+16+31+62+124+248

A perfect number is such a number, sum of whose factors is equal to twice the number. In other words, sum of all its factors except the number itself is equal to the number.
Considering the second definition>
6
28
6 and 28 are the two perfect numbers within 100

A perfect number is a number where all the numbers that divide evenly into it, added together equal the original number...ex. 6. 1,2,3 all divide into 6 evenly, add 1+2+3 together and you get your original number of 6. 28 is perfect because 1+2+4+7+14=28.

1 + 2 + 3 = 6 is an example. If you can add one side of the = sign and get the same answer that you would get if you multiplied the numbers together.

Read the link below
An integer (N) such that the sum of all its divisors equals N
e.g. 28
28 is divisible by 1,2,4,7,14
1 + 2 + 4 + 7 + 14 = 28

perfect no is a no whose factors r all integers
like120
its fators r 1,2,3,4,5 ;all r integers
120=1*2*3*4*5
