Q. Measurements of a room are 7m50cm, 6m8cm3m75cm. Find the length of the longest rod that can measure all the three dimensions of the room.
Convert to centimeters: Convert all measurements to centimeters for uniformity. 7m50cm=750cm, 6m8cm=608cm, 3m75cm=375cm.
Find GCD for longest rod: Find the greatest common divisor (GCD) of the three measurements to determine the longest rod that can measure all dimensions.GCD of 750, 608, and 375.Using the Euclidean algorithm:750 and 608: 750−608=142608 and 142: 608−4×142=48142 and 6080: 60816080 and 6083: 60846083 and 6086: 6087GCD is 6086.
