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.
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.
It is called the prime factorisation (or prime decomposition) of the composite number.
Fundamental theorem of arithmetic :- Every composite number can be expressed (factorized) as a product of primes, and this factorization is unique . apart from the other in which factors occur.
A composite number. The product of two primes is sometimes called a semiprime.
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.
50 = 2*5*5
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.
