Hope this is correct because did not give the full question

Step-by-step explanation:

Prime factorisation of a natural number is unique.

80= 2 × 2 × 2 × 2 × 5

85 = 5 × 17

90 = 2 × 3 × 3 × 5

LCM of 80,85 and 90 =2 ×2 × 2 × 2 × 3 × 3 × 5 × 17 = 12240

Minimum distance each should walk so that they can cover the distance in complete

steps = 12240 cm = 122.4 m
