Can composite numbers be written as the product of prime factors?
Yes. Composite numbers can be written as the product of prime factors.
Why all numbers other than square numbers have an even number of factors?
Consider a number k. Let m be the square root of k : since k is not a square number, m is not an integer and so m cannot be a factor of k.
Suppose p is a factor of k and suppose p< m.
Then k has another factor q such that k = p*q and since p < m, then q> m.
Thus, for every factor smaller than the square root, there is another factor that is larger than the square root. That is, the factors come is distinct pairs and so there is an even number of factors.
What composite number can be expressed as product of its factors?
None.
A composite number c must have a prime factor psuch that 1 < p < c.
Therefore the product of c's factors must be at least p*c which must be greater than c.
Is 4 composite or prime number?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 4 is composite.

32 is a composite number while 13, 19 and 29 are prime numbers
What is the comparison between prime number and composite number?
A prime number is a whole number that has two factors which are itself and one.
where as,
A composite number has factors in addition to one and itself.
