What is the trick for all prime numbers?

Excuse me, could you clarify what you mean by "the trick for all prime numbers"? Prime numbers, by definition, are numbers greater than 1 that have no divisors other than 1 and themselves. There isn't necessarily a "trick" to finding or identifying all prime numbers, but there are methods and algorithms that can be used to determine if a given number is prime or not. Are you referring to a specific method or technique for identifying prime numbers? If so, could you please provide more context or detail?
