two tankers contain 620 litres and 840 litres of diesel respectively. Find the maximum capacity of a container which can measure the diesel of both the tankers in exact number of times

Use Prime factorisation and find the factors of 620 and 840.

840 = 2³ * 5 * 3 * 7
620= 2² * 5 * 31

To find the HCF take the common factors of both 620 and 840.

HCF= 2² * 5
        = 20

Therefore, The maximum capacity of a container which can measure the diesel of both tankers is 20.
