Here, we need to find the LCM of the 3 numbers.
If we take the numbers as 1cm 2cm and 3cm, the LCM would be 6cm. This means that all the 3 people will meet at 6cm.
LCM of 80, 85 and 90 = 2×2×2×2×3×3×5×17
= 12240 cm
Which means that they will have to cover a minimum distance of 122m and 40cm to meet.
Hope this helps :)
