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.
Answer & explanation
Correct answer: option 3
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
