only answer​

Answer 1

Answer:

144 is the answer

The least square number which is exactly divisible by 3, 4, 8 and 9 = L.C.M of 3, 4. 8 and 9

Now, L.C.M of 3, 4, 8 and 9 is

L.C.M of 3,4, 8 and 9 =

LCM = 2 3,4,8,9

2 3,2,4,9

2 3,1,2,9

3 3,1,1,9

3 1,1,1,3

1,1,1,1

2×2×2×3×3=72

Pair of 2 is not completed. To make it a perfect square, the number should be multiplied with 2

Now, 72 ×2=144

The least square number which is exactly divisible by 3, 4, 8 and 9 is 144
