Cicadas are natural mathematicians. In order to avoid their natural predators (in this case, the wasp), they emerge from hibernation in "a prime number" of years. For example, if the emergence period of a wasp is every years, selecting 4 or 6 or even 9 years emergence period for the cicadas, means that their population would be wiped out in a few years. But, by selecting a prime emergence period, say years, they are assured not to meet their predators for a very long time. In this case, if cicadas and wasps emerged the same time today, it would take another years for them to again see each other.
In a theoretical environment, a particular species of cicadas selects to emerge every (n-th Fibonacci number) days, while the predator wasps selects emergence period of (m-th Fibonacci number) days. Given the values of n and m, and assuming that the insects emerge at the same time, today, in how many days will they again emerge together.
For example, if the cicadas selected , and the wasps chose , they will emerge at the same time again in days.
NOTE: You are given: and . Since the answer can be a huge number, please present your answer "modulo ".
