We have,
             x^2yz =x \times x \times y \times z
              xy^2z =x \times y \times y \times z
             xyz^2 =x \times y \times z \times z
Therefore,   on factorization we get,
x^2yz+xy^2z+xyz^2 =(x \times x \times y \times z)+(x \times y \times y \times z)+(x \times y \times z \times z)                                         

 =( x \times y \times z)(x + y + z)
 =xyz(x+y+z)
