Answer»

This is not a PERFECT square because '3' is left UNPAIRED. To make it a perfect square, we need to make a pair of this remaining 3. So, we need to multiply the given NUMBER with 3.  2352 = 2 x 2 x 2 x 2 x 7 x 7x 3since 3 is not in pair multiply the number with 3therefore,7056 = 2 x 2 x 2 x 2 x 3 x 7 x 7  x 3hence, 7056 is the SMALLEST multiple.Note: If a number has its UNIT digit '2', it can't be a perfect square.
