Question

find the least square number which is divisible by 3,6,9,12

Answer 1

Answer:

The least number which is exactly divisible by each  of  the number 4,6,9,12 and 14 is their L.C.M

The L.C.M of 4,6,9,12 and 14 is 252.But 252=2×2×3×3×7=(2×2)×(3×3)×7

The last factor 7 has no pair, so in order to make 252 a perfect square , it must be multiplied with 7

So 252×7=1764=2×2×3×3×7×7

Hence 1764 is the required number
