see if the last answer after  matrix multiplication is column matrix    (  1  0  0  ) and  one of the factor is column matrix(  x    y    z  ) .. 
then A must be of the  
form  1 x 1.   because( matrix of the form 1x1 ) ×(matrix multiplication) matrix of the form 1x3 gives a matrix of the form 1x3 .    
Hence. n = 1
 
  please tell me if i am wrong
