Shira has now decided to decorate her kitchen of height H and width W more precisely, she wants to tile the floor.
After experimenting with different tile materials of Shira and her friend Linnea.
Linnea advised that it would be more eye-catching if the height and width of the tiles are as wide as possible. In other words the dimension of the tiles must be a square with maximum area that perfectly fit her kitchen without any scraps. Note that the dimension must be integers.
But Shira doesn’t know what the height of the square-tile will be. Can you help her ?
