What does prime number mean? Is it related to prime numbers?

Many students know prime numbers, so what is the specific meaning of prime numbers? Let's take a look together.

The meaning of prime number is also called prime number, which refers to a natural number with no other factors except 1 and itself. On the contrary, it is called a composite number. 1 and 0 are neither prime numbers nor composite numbers. There are infinitely many prime numbers, mainly 2, 3, 5, 7, 1 1, 13, 17, 19, 23, 29, 3 1, 37, 4.

In natural numbers, a÷b=c(a, B and C are all integers), and B is a factor of A ... For example:

12÷3=4, and 3 is a factor of 12.

Like 7, there are only factors 1 and 7, so 7 is a prime number, and the factors of 7 1 are 1 and 7 1. Accordingly, the factors of 12 are: 1, 2, 3, 4, 6, 12, and 12 is a composite number.

The memory method of prime number law first remembers that the product of 2 and 3 is a prime number within 6. 100, which is generally around the multiple of 6. For example, 5,7, 1 1, 13,19,23,29,31,37,41,43 ... only 25,35. Therefore, the two numbers before and after the multiple of 6 in 100 must be prime numbers as long as they are not multiples of 5 or 7. According to this feature, you can remember the prime numbers within 100.

The above is some information about prime numbers, I hope it will help you.
