It is called the prime factorisation (or prime decomposition) of the composite number.
The prime factorization
It is the product of two primes and so is a composite.
Assuming you are referring to the prime factors of the number, the product of the prime factors of any composite number is equal to the number itself.
Writing a number as the product of its prime factors is called prime factorization.
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.

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.
Expressing 15 as a product of its primes is 3 x 5 = 15 Composite numbers can be broken down into a product of prime numbers.
A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.
It is the product of two primes and so is a composite.
That's known as a prime factorization.
Assuming you are referring to the prime factors of the number, the product of the prime factors of any composite number is equal to the number itself.
The number 39 is a composite number. 39 = 3 x 13. Because 39 can be written as a product of primes (3 and 13), it is, by definition composite.
That's a prime factorization.
The only factors or divisors or 3 are 1 and the number 3 itself. The definition of a prime is a number whose only factors are 1 and itself so 3 fits this definition.Any composite number can be broken down into a product of primes. If you try, you will see there is not product of primes that equals 3.
7 is a factor of 77 so it cannot be a prime. So it has to be composite.It is composite since 7 x 11 is 77 and those are both primes. That is to say, it is the product of two primes and that makes it composite.
Writing a number as the product of its prime factors is called prime factorization.
