7. Three tankers contain 403 litres, 434 litres and 465 litres of diesel respectively. Find the maximum capacity of a container that can measure the diesel of the three containers exact number of times.
Maximum capacity of the required tanker =HCF of 403,434,465
403=13 31
434=2 7 31
465=3 5 31
HCF=31
Hence the maximum capacity of a container that can measure the diesel of the three containers the exact number of times is 31.
