Explanation

First, convert the dimensions to centimeters: length = 437 cm, width = 323 cm. The side length of the largest square tile is the highest common factor (HCF) of 437 and 323, which is 19 cm. The number of tiles required = (length × width) ÷ (side of tile)² = (437 × 323) ÷ (19 × 19) = 391.
