    1. Best Answer

      L.C.M. of 4, 9 and 10 is 180.
      Prime factors of 180 = 2 x 2 x 3 x 3 x 5
      Here, prime factor 5 has no pair. Therefore 180 must be multiplied
      by 5 to make it a perfect square.
      ∴ 180 x 5 = 900
      Hence, the smallest square number which is divisible by 4, 9 and 10
      is 900.
