Squares and rectangles fascinated the famous Dutch painter Piet Mondriaan. One night, after producing the drawings in his 'toilet series' (where he had to use his toilet paper to draw on, for all of his paper was filled with squares), he dreamt of filling a large rectangle room with small square tile.
Expert as he was in this material, he saw at a glance that he'll need a computer to calculate the least number of tiles to fill the large rectangle room whose dimensions were real number, as well. Help him, so that his dream won't turn into a nightmare!
The input file contains several test cases. Each test case is made up of two real numbers: the height h and the width w of the large rectangle (0.01<=h<=99.99,0.01<=w<=99.99). Input is terminated by h=w=0.
For each test case, output the least number of the given rectangle can be filled with small squares tile.
This figure shows the first data in Sample Input.
