What's the difference between prime, prime, divisor, composite and factor?

Prime, also known as prime, is a positive integer that can only be divided by 1 and itself. For example, 2, 3, 5, 7, etc. 2 is the only even prime
On the contrary, in addition to 1 and itself, there is at least one number that can divide it, such as 4, 9, 12, etc
If a number can divide another number, it is called the divisor of another number
The above concepts are generally studied in the range of positive integers
