Question

the tankers. Moreover this capacity should be maximum. Thus the maximum capacity or
such a container will be the HCF of 850 and 680. The HCF of 850 and 680 is 170.
Therefore, maximum capacity of the required container is 170 litres. It will fill the first
container in 5 and the second in 4 refills.

the length of longest stick that can measure all the dimensions of the room in exact number
of times ?
HCF of co-prime numbers 4 and 15 was found as follows by factorisation:
4= 2 x 2 and 15 = 3 x 5 Since there is no common prime factor, HCF of 4 and 15 is 0.
Is the answer correct? If not, what is the correct HCF?
