Answer:
Step-by-step explanation:
LCM of 5, 6 8 is 5×6×8 = 240
Now prime factorise 240
We get
240 = 2×2×2×2×3×5
If we see carefully there are two pairs of 2 but 3 and 5 are unpaired
So if we multiply the above product of prime factors by 3×5 =15 we get our answer
=> 240 × 15
= 3600
This is the smallest perfect square number divisible by 5, 6 and 8
Hope it is clear
