Problem: a room is 7 meters 68 centimeters in length and 4 meters 32 centimeters in width . find the least number of square tiles of equal size required to cover the entire floor of the room .
Rationale: "let us calculate both the length and width of the room in centimeters . length = 7 meters and 68 centimeters = 768 cm width = 4 meters and 32 centimeters = 432 cm as we want the least number of square tiles required , it means the length of each square tile should be as large as possible . further , the length of each square tile should be a factor of both the length and width of the room . hence , the length of each square tile will be equal to the hcf of the length and width of the room = hcf of 768 and 432 = 48 thus , the number of square tiles required = ( 768 x 432 ) / ( 48 x 48 ) = 16 x 9 = 144 answer : b"
annotated_formula: divide(multiply(add(multiply(7, const_100), 68), add(multiply(4, const_100), 32)), multiply(gcd(add(multiply(7, const_100), 68), add(multiply(4, const_100), 32)), gcd(add(multiply(7, const_100), 68), add(multiply(4, const_100), 32))))
