Prime numbers are also called prime numbers.

Prime numbers are also called prime numbers, and there are infinite numbers. A natural number greater than 1 is called a prime number if it cannot be divided by other natural numbers (except 0) except 1 and itself; otherwise it is called a composite number. According to the fundamental theorem of arithmetic, every integer greater than 1 is either a prime number itself or can be written as the product of a series of prime numbers; and if the order of these prime numbers in the product is not considered, then the written form is unique.

In the field of natural numbers, prime numbers are indivisible numbers and are the basic elements that make up all natural numbers. For example, 10 is the product of 2 and 5. There are infinite prime numbers, so there are infinite elements in the arithmetic world. All objects, theorems and methods in the arithmetic world are composed of its basic elements, prime numbers.

Natural numbers with only two positive factors, 1 and itself, are called prime numbers (or prime numbers). (For example, from 2÷1=2, 2÷2=1, we know that the only factors of 2 are 1 and itself 2, so 2 is a prime number. The opposite is composite numbers: "Numbers with other factors besides 1 and itself are called composite numbers." For example, 4÷1=4, 4÷2=2, 4÷4=1. Obviously, besides 1 and itself 4, 4 also has the factor 2, so 4 is a composite number.)

The prime numbers within 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. There are 25 prime numbers within 100.
