TO FIND: minimum distance each should walk so that all can cover the same distance in complete steps.
The distance covered by each of them is required to be same as well as minimum. The required distance each should walk would be the L.C.M of the measures of their steps i.e. 80 cm, 85 cm, and 90 cm,
So we have to find the L.C.M of 80 cm, 85 cm, and 90 cm.
80 = 24 x 5
85 = 17 x 5
90 = 2 x

x 5
L.C.M of 80, 85 and 90 = 24 x

x 5 x 17 = 12240 cm
Hence minimum 12240 cm distance each should walk so that all can cover the same distance in complete steps
