42m = 2 * 3 * 7
49m = 7 * 7
84m = 2 * 2 * 3 * 7
so the greatest length of rod which can measure exactly 42m , 49m , 84m is 7m
49m = 7 * 7
84m = 2 * 2 * 3 * 7
so the greatest length of rod which can measure exactly 42m , 49m , 84m is 7m

Answer:
7 meters
Step-by-step explanation:
In order to find the greatest length of the rod, we'll find the GCF (greatest common factors) of the given numbers.
Let us write the factors of the numbers.
42 = 2×3×7
49 = 7×7
84 = 2×2×3×7
GCF is the common term among all the factors.
We can see that , the common number is 7.
Hence, GCF = 7
Therefore, the greatest length of the rod that can measure the given measurement is 7 m.
