Question

Get the solution .. in a morning walk 3 persons step off together and their steps measure 40,42,45 cm . what is the minimum distance each should walk so that each cover the same distance in complete steps

Answer 1

That means we have to find out the lowest common multiple of 40,42 and 45

40= 2*2*2*5
42= 2*3*7
45= 3*3*5

So LCM = 2*2*2*3*3*5*7 = 2520

That means they have to walk for 2520 cm = 25.20 m to cover same distance.
