42 = 2×3×7
49 = 7×7
84 = 2×2×3×7
HCF of 42, 49 and 84 is 7
the greatest length of the rod which can measure exactly 42m,49m and 84m is 7 m
the number of times the rod of 7m is contained in 42m = 6 times
the number of times the rod of 7m is contained in 49m = 7 times
the number of times the rod of 7m is contained in 84m = 12 times
49 = 7×7
84 = 2×2×3×7
