It does not! The number 7 has fewer factors!
One needs the composite number before he can find its factors. Thus the solution I shall give is ∞.
A number will have an odd number of factors if and only if one of those factors is the square root of the number. This is because any factor of a number you can find must pair up with another factor of that number, and multiply to give the number. The only exception is when the factor would be paired with itself. In other words, be the square root. 81 is a square number, and so the factor 9 (square root of 81) will not pair with any other factor, meaning 81 will have an odd number of factors. 40 has an even number of factors, because it is not a square number, and so all its factors can pair up.

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
24 is not a perfect number as its factors (excluding 24) are: 1, 2, 3, 4, 6, 8 and 12 which add to give 36 not 24. However, 28 is a perfect number as its factors (excluding 28) are: 1, 2, 4, 7 and 14 which add to give 28.
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!

Any number that has more than 2 factors is a composite number
One needs the composite number before he can find its factors. Thus the solution I shall give is ∞.
A square number, like 4, 9 and 25.

It is not possible to give a sensible answer to this question. The phrase "common factor" refers to a factor that is COMMON to two or more numbers. You have only one number in the question!Furthermore, whatever the other number or numbers were, the least common factor of any set of integers is 1.
