Because that's the definition of a composite number (or, at least, it's logically equivalent to the definition).
1 is neither a prime or composite number
The product of two prime numbers will be composite.
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.
A composite number is an integer which is the product of two or more integers which greater than 1.
Yes. Composite numbers can be written as the product of prime factors.
Prime numbers have only two factors: one and themselves. By definition, your product would have more than that: one, the product and at least the two numbers that created the product. It has to be composite.
Yes, of course. In fact the product of any two numbers is composite unless one of them is 1.
Because that product would have both of the two numbers as factors, giving it at least a total of 4.
Prime factorization is writing a composite number as a product of prime numbers.
if divide the prime numbers by the compositenumber it will give you a greater number that is either a prime number or composite.
There are no such numbers. The smallest set of three consecutive composite numbers is {8, 9, 10} and the product of these numbers is 720.
No not always because composite numbers can be the product of 2 or more prime factors
