Answer 2

Answer:

900

Step-by-step explanation:

LCM of 5,6 and 12 is 2×2×3×5 = 60

We see that prime factor 3 and 5 not in pairs.Therefore 60 is not a perfect square.

In order to get a perfect square, each factor of 60 must be in pair. So , we make pairs of 3 and 5 . Therefore 60 should be multiplied by 3×5 = 15

Hence the required number is 60 × 15 = 900
