Prime number is prime number.

prime number (prime number), also known as prime number, there are infinite. A Nature number that is greater than 1 and is not divisible by any other Nature number except 1 and itself (except 0) is called a Prime number); Otherwise it is called a combined number. radical According to the fundamental theorem of arithmetic, every whole number that is greater than one is either itself a prime number or can be written as a series of prime number products; And regardless of the order of the number of these qualities in the product, then this formality is unique.

In the field of Nature number, the prime number is a non-divisible number, which is the basic elemental of all Nature numbers. for example, 10 is the product of 2 and 5's, and there are infinitely many prime numbers, so there are infinitely many elemental numbers in the arithmetic world. All objects, theorems and methods in the world of arithmetic both are composed of a number of their basic elemental qualities.

Only 1 and its own two positive divisor Nature number, called prime number (or prime number). (For example, 2÷1=2, 2÷2=1, 2's divisor has only two approximate numbers of 1 and itself 2, so 2 is the prime number. The opposite of and is a combination number: "There are divisor numbers other than 1 and its own two divisor numbers, called a combination number." For example: 4÷1=4, 4÷2=2, 4÷4=1, it is clear that 4's divisor has divisor 2 in addition to 1 and 4 itself, so 4 is a combined number.

100 has 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 in the endoplasmic number, and there are 25 endoplasmic numbers in 100.
