B"In Vika's hometown, Vladivostok, there is a beautiful sea. Often you can see kids skimming stones. This is the process of throwing a stone into the sea at a small angle, causing it to fly far and bounce several times off the water surface. Vika has skimmed stones many times and knows that if you throw a stone from the shore perpendicular to the coastline with a force of f , it will first touch the water at a distance of f from the shore, then bounce off and touch the water again at a distance of f - 1 from the previous point of contact. The stone will continue to fly in a straight line, reducing the distances between the points where it touches the water, until it falls into the sea. Formally, the points at which the stone touches the water surface will have the following coordinates: f , f + (f - 1) , f + (f - 1) + (f - 2) , ... , f + (f - 1) + (f - 2) + ldots + 1 (assuming that 0 is the coordinate of the shoreline). Once, while walking along the embankment of Vladivostok in the evening, Vika saw a group of guys skipping stones across the sea, launching them from the same point with different forces. She became interested in what is the maximum number of guys who can launch a stone with their force f_i , so that all f_i are different positive integers, and all n stones touched the water at the point with the coordinate x (assuming that 0 is the coordinate of the shoreline). After thinking a little, Vika answered her question. After that, she began to analyze how the answer to her question would change if she multiplied the coordinate x by some positive integers x_1 , x_2 , ... , x_q , which she picked for analysis. Vika finds it difficult to cope with such analysis on her own, so she turned to you for help. Formally, Vika is interested in the answer to her question for the coordinates X_1 = x cdot x_1 , X_2 = X_1 cdot x_2 , ... , X_q = X_{q-1} cd"...
