4 is a composite number (2 x 2), and it is less than 5.
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 bIt 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.

4 is.
3 less than the product of 9 and a number
Literally every single even number less than 1000 is a composite number other than 2 which is prime.
That is how a composite number is defined! It cannot be prime if it is a product of two integers that are bigger than one.
It is 19 which is a prime number
Product of two prime numbers is a composite number. e.g. 2 x 3 = 6, 3 x 17 = 51 etc. But, why the result is a composite number? Definition of composite number makes it much clear: A number which can be expressed as the product of prime numbers is called a composite number. Also, it has more than two factors. So, product of two primes is a composite number.
