No The first perfect number is 6 because 1, 2 and 3 are the proper positive divisors and 1 + 2 + 3 = 6 The next perfect number is: 1 + 2 + 4 + 7 + 14 = 28

The second perfect number after 6 is 28. The sum of the factors of 28, excluding itself, is 1 + 2 + 4 + 7 + 14 = 28.

It isn't a perfect number.A perfect number is a number which is the sum of its proper divisors (including 1, but excluding itself).The divisors of 20 are 1, 2, 4, 5, 10.1 + 2 + 4 + 5 + 10 = 22 => 20 is not a perfect number.An example of a perfect number is 28:The divisors of 28 are 1, 2, 4, 7, 141 + 2 + 4 + 7 + 14 = 28 => 28 is a perfect number.

Because numbers are infinite, there is an infinite number of answers. e.g. What number should be added to 2 to make a perfect square? 2+2=4 (a perfect square) 2+7=9 (a perfect square) 2+14=16 (a perfect square) 2+23=25 (a perfect square) etc... Did you have a specific number in mind.

it is perfect i believe the factors are 1,2,4,7,and 14

A perfect square number is a number that can be expressed as the product of two same common integers. For instance, 16 is a perfect square since it is expressed as 4 x 4. 14 is not the perfect square since it can't be expressed as two common integers. The factors of 14 are 2 and 7.

A number is perfect if all it's factors (barring itself) sum to make the original number. In this case, the factors of 28 are 1,2,4,7 and 14. Added up, these equal 28. Thus, 28 is a perfect number.

The square root of 175 is 13.23 (2 decimal places) so it is not a perfect square number. The closest perfect squares are 169 (13 squared) and 196 (14 squared).

28 is a perfect number. Add the factors of the number, excluding the number itself. 28: 1 +2 +4 + 7 + 14 = 28. The sum of its factors is the same as the number! The next perfect numbers are 496, 8128, 33550336, 8589869056, 137438691328, 2305843008139952128, 2658455991569831744654692615953842176, and 191561942608236107294793378084303638130997321548169216.
