It's a perfect square.

When does a number has 3 distinct factors?
When the number is a square of a prime number. Of course, it will have a repeated factor, but it will still only have 3 distinct factors. 4, 9, 25, 49, 121 are some examples.

What sort of numbers have an odd number of factors why?
A perfect square has an odd number of distinct factors, because two of its factors are the same number.
Does a perfect square number have even or odd number of distinct factors?
An odd number.
How many distinct factors does the number 64 have?
Seven distinct factors.
How is 28 the perfect number?
First of all, to know if a number is abundant, deficient, or perfect, you need to know all the factors of your given number. The factors of 28 are 1,2,4,7,14, and 28. Add your proper factors -or the factors except itself- and determine if the sum of the proper factors is below (deficient), above (abundant), or the exact same amount (perfect). In this case, if you add the proper factors, it equals exactly 28. Because it is exact, it is perfect! =)
What is the Perfect number and what is the perfect number after 28?
A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496
Why is 25 a composite number?
A composite number is a number that is not a prime number, ie it has more than two distinct factors. The factors of 25 are 1, 5, 25 - three distinct factors.
How many distinct factors does the number 36 have?
Nine factors.
What type of number has an odd number of factors?
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.
What type of factor has an odd number of factors?
A perfect square has an odd number of factors.
Is 42 a perfect number?
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.)Use the definition of a perfect number!

Are there any quasi-perfect numbers?
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.
