The sides of a triangular field are 62 m, 186 m and 279 m. Find the greatest length of tape that would be able to exactly measure each of them without any fractions.

62 m 93 m 31 m 30 m

31 m

Sides = 62 m, 186 m, and 279 m 62 = 2 x 31 186 = 2 x 3 x 31 279 = 3 x 3 x 31 HCF(62, 186, 279) = 31 The greatest length of tape that would be able to exactly measure each of them without any fractions = 31 m
