How many years after an appearance of 13 year and 17 year cicadas together will both types of cicadas appear together again?
342years
You often see the skins of these insects stuck on trees?
Cicadas.
Why don't 17 year old cicadas and 13 year old cicadas appear together?
This question is equivalent to asking what multiples of 13 and 17 are equal, and more specifically, what is the lowest multiple of 13 that equals a multiple of 17 or what is the lowest multiple of 17 that equals a multiple of 13. Since 13 and 17 are prime, they have no factors in common. This means that the lowest common multiple is equal to 13 x 17 = 221. Therefore, it will be 221 years before the 13 and 17 year cicadas appear together again.

Why do cicadas come out during prime number years?
Suppose the cicadas come out every C years and a predator comes out every P years. Then the life cycles of the predator and the cicadas will coincide every LCM(C, P) years. The predator will want it to happen as often as possible while the cicadas want that to happen as seldom as possible. If C is co-prime with P then the cycles coincide after CP years - which is best for the cicada.Suppose the cicadas come out every C years and a predator comes out every P years.
