To think of cicadas as "deciding" something is anthropomorphizing; that is, using words that describe human attributions with things that don't really think as humans do. What probably happened is that those cicadas which happened to have a prime number cycle tended to avoid having predators match their periodic appearances and so increased relative to those that didn't, and as a consequence, got eaten. This is Natural Selection. Incidently, only Periodic cicadas have prime number cycles (17 or 13 years); there are also Annual cicadas which as their name implies, appear every year.
Numbers that have more than two factors are not prime numbers because prime numbers have only two factors.
Cicadas likely evolved to have prime-numbered life cycles as a strategy to avoid synchronization with other insect species or predators. By having longer life cycles that are not easily divisible by other common periods, cicadas can reduce competition and increase their chances of survival and reproduction. This unique adaptation may have provided an evolutionary advantage, leading to the prevalence of prime-numbered life cycles among cicadas.
The way to know the Prime Numbers is to find out if they can only Multiplied Once ,The way to know Composite Numbers is to find out if they can be Multiplied Twice
Prime numbers only have two factors.

i know what 2 prime numbers are. you want to know? do you really want to know. well, heres the answer. i don't know what 2 prime numbers are but i do know what 2 prime numbers are. sorry. hahaha. :)
You can do prime factorization with probably every numbers. You have to be specific about the numbers you want to know.

2 and 3 Prime numbers have only two factors.
It is impossible to know the number of prime numbers because there is an infinite number of them.
Prime numbers only have two factors.
They are relatively prime.
Well, isn't that a happy little math problem we have here! Let's see, the two prime numbers that add up to 78 are 41 and 37. Just like in painting, sometimes you need to mix different colors to create something beautiful. Happy calculating!
Impossible to know; prime numbers are infinite.
