Question

Three children are walking together. Their steps measure 36 cm, 72 cm and 90cm respectively. If they step out together, after what distance will they step together again?

Is this sum finding L.C.M?

Answer 1

Yes you have to find the L.C.M of 36 cm, 72 cm and 90cm respectively

L.C.M=2×2×2×3×3×5= 360cm

and the answer is 360 cm or 3.6 m.
