Perfect squares have an odd number of factors.
Any multiple of 4 has perfect square factors.
All numbers have factors. Some factors are perfect squares. We call these perfect square factors. 9 is a perfect square factor of 27.
No. Perfect square numbers have an odd number of factors.
A perfect square.
Perfect squares are numbers with an odd number of factors.
The perfect numbers under forty are 6 and 28.

A perfect square.
Pairs of numbers.
All compound numbers that are not perfect squares.
Prime numbers have two factors. The sum of their proper divisors is always 1.
The same number is multiplied with itself to form a perfect square i.e. a perfect square has real and repeated equal numbers as factors.
There are 31 perfect squares in that range.

A "perfect number" is a number that is equal to the sum of its factors (that is, the factors that are less than the number). As far as I know, there is no concept of "quasi-perfect" in number theory.
Numbers can't be divided by multiples. They get divided by factors. Factors go into numbers, numbers go into multiples.
A square number or a perfect square.
A perfect square has an odd number of factors. Factors of numbers always come in pairs -- except for perfect squares. Since the square root of a perfect square is listed only once on the list of factors, it results in a list with an odd number of factors.
If the sum of all a number's factors (factors that are smaller than the number itself) is equal to the number itself, the number is said to be "perfect". For example, the factors of 6 (excluding 6 itself) are 1, 2, and 3; and the sum of these numbers is exactly 6. The smallest perfect numbers are 6, 28, 496, 8128. It isn't known whether the set of perfect numbers is finite or infinite. Also, it isn't known whether there are any odd perfect number; all known perfect numbers are even.
No, the product of two factors that are the same is a perfect square. Common factors are numbers that divide evenly into a given set of numbers.
They are numbers that are NEAR PERFECT. a near perfect number is when its factors (exept the actual number) are added up and ALMOST equal the number ex. 16x1/2x8/4x4/ so its factors are 1,2,4,8 and 16 so add them ( exept the actual number) 1+2+4+8=15 so its NEAR PERFECT and a perfect number is a number that all its factors equal to its number ex. 6-1,2,3,6 are its factors all together-1+2+3=6 those are NEAR PERFECT and PERFECT numbers
Use the definition of a perfect number! Add the factors; if the sum of all the factors (excluding the number itself) is equal to the number, it is a perfect number, otherwise it isn't. (Actually, the only perfect numbers less than 100 are 6, and 28.)
