1,Each composite number can be written as a multiplication of several prime numbers.

Each prime number is a factor of this composite number and is called the factored prime factor of this composite number. Decomposing prime factors only for composite numbers

2,Prime factors (or prime factors) in number theory are prime numbers that divide a given positive integer.

Two positive integers without a common prime factor are called coprimes. Because 1 has no prime factors, 1 is coprime with any positive integer (including 1 itself).

The factorization of positive integers can be expressed as a series of prime factors multiplied. Prime factors such as repetition can be expressed exponentially.

According to the basic theorem of arithmetic, any positive integer has a unique prime factorization. A positive integer with only one prime factor is a prime number.

Composite prime

1,Prime numbers are also called prime numbers, and there are infinite. A natural number greater than 1 cannot be divisible by other natural numbers (prime numbers) except 1 and itself，

In other words, the number has no factors other than 1 and itself; otherwise it is called a composite number.

2,According to the basic theorem of arithmetic, every integer greater than 1 is either itself a prime number or it can be written as the product of a series of prime numbers;

And if you don't consider the order of these prime numbers in the product, the written form is unique. The smallest prime number is 2.

3,Composite numbers, mathematical terms, the English name Composite number, refers to the natural number except that it can be integer and 1

Numbers that are divisible by other numbers (excluding 0). The opposite is the prime number (the factor is only 1 and itself, such as 2, 3, 5, 7, 11, 13, etc., also known as prime numbers),

And 1 is neither a prime nor a composite number. The smallest composite number is 4.

4,One way to classify composite numbers is to calculate the number of prime factors. A composite number with two prime factors is called a semiprime number, and a composite number with three prime factors is called a wedge number.
