Answer 2

Answer:

LCM of 70,75,80

Step-by-step explanation:

To find minimum distance each can walk to cover same distance the LCM of the size of steps.

By prime factorisation,

70= 2×5×7

75= 3×5×5

80=2×2×2×2×5

LCM(70,75,80)= 2×2×2×2×2×3×5×5×7= 16800 cm

Hence minimum distance = 16800cm = 168 m.
