Answer:
answer is 3600
Step-by-step explanation:
LCM of 8,15 and 20 = 2*2*2*3*5
= 120
hence,prime factor 2,3 and 5 do not have their respective pairs. Therefore,120 is not a perfect square.
Therefore,120 should be multiple by 2*3*5 to obtain a perfect square.
hence, the required square number is
120*2*3*5 = 3600
