GeniusShweta: 2520 CM
mhesh1: exactly.
Manassvi: I think we should find HCF
GeniusShweta: NO....LCM
mhesh1: mm never really understood which one to use when.
Manassvi: So can you explain
mhesh1: 'least common multiple' and they need the least steps, so I went for the lcm.
Manassvi: Kk

2520? I guess, all you have to do is to find the lcm of 40, 42, 45.

Here we have to find LCM of the three foot steps
Hence.,LCM(40,42,45)=2520steps
