Question

two tankers contain 850 liters and 680 liters of petrol respectively.find the maximum capacity of ac container which can measure the petrol of either tank in exact number of liters

Answer 1

here, we have to find the highest common factor(hcf)

by prime factorization,

850 = 2x5x5x17

680 = 2x2x2x5x17

HCF = 2x5x17 = 170

so the capacity of such tanker should be 170 litres.
