A Thaparian has been solving a lot of mathematical problems recently. He was learning __Euler Totient Function__ and found the topic quite interesting. So, he tried solving a question on __Euler Totient Function__. He will be given two numbers $L$ and $R$. He has to find the probability that the __Euler Totient Function__ of a number in the range $[L, R]$ is divisible by a number $K$. Note: __Eule
