It is called the prime factorisation (or prime decomposition) of the composite number.
the prime factorization of the number

composite
Prime factorization is writing a composite number as a product of prime numbers.
.1 is not prime, since a prime has exactly two positive divisors.1 is not composite since it cannot be written as the product of primes.The number 1 is not called a prime OR composite number. It is called a f*cking UNIT !
When a composite number is expressed as the product of its prime factors, we call that the prime factorization.
A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.
A composite number. The product of two primes is sometimes called a semiprime.
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.
As for example 98 as a product of its prime factors is: 2*7*7 = 98
When a composite number is expressed as a product of its prime factors, the prime factorization of the composite number has been performed.
