20cm is the greatest length that can be used to measure exactly the given lengths.
Step-by-step explanation:
Given the three lengths,
2m = 200cm
60 cm = 60cm
6m = 600cm
12m = 1200cm
Now, we have to find the HCF of 200, 60, 600, 1200
200 = 2 * 2 * 2 * 5 * 5
60 = 2 * 2 * 3 * 5
600 = 2 * 2 * 2 * 3 * 5 * 5
1200 = 2 * 2 * 2 * 2 * 3 * 5 * 5
H.C.F = 2 * 2 * 5 = 20
Thus, 20cm is the greatest length that can be used to measure exactly the given lengths.
