Answer 1

Answer:

720 cm

Step-by-step explanation:

GIVEN: Their steps measure 240 cm, 90 cm, and 120 cm.

We have to find the L.C.M of the measures of their steps to calculate the required distance each should walk.

L.C.M of 240 cm, 90 cm, and 120 cm.

240=2^4 ×3×5

90=2×3^2×5

120=2^3×3×5

L.C.M(240,90,120)= 2^4×3^2×5

                              =720 cm

Hence, the minimum distance each should walk so that all can cover the same distance in complete steps is 720 cm
