Product of a Prime number and a composite number results in a composite number.
Now consider the product of a composite number(a) and a prime number(b) is equal to c.
i.e. c = a x b
It is clear that c is divisible by both a and b.
Also c is divisible by itself and 1, this means that c has more than two factors.
A number having more than two factors is composite, therefore product of a prime number and a composite number results in a composite number.
