Step-by-step explanation:
Prime factorization says that, if a number is prime then the only way it can be factored is, 1 times the number itself.
But if the number is composite, it can be expressed as a product of prime factors. This method is called prime factorization.
For example: 12 is a composite number, it can be written in the form of prime factorization as,

Here we can see that 12 is expressed as the product of primes only. This is called prime factorization.
