        Divisor  Patterns

           can  be  divided exactly by { .
        6                             6 3.  2.  1}
        21           ;;i.{21.  7.  3.  1}
        1 3           {1  3.  1 }
        In  this game we.shall forget about the divisor which is  the same  as  the number we started
        with.
        1 2           {.M'.  6.  4.  3.  2.  1}

        10            {.0.  5.  2.  1}
        The  sum  of the  divisors of 10 is :   5+2+1  =  8



            Complete these  patterns:

                       5  r 3 + 1           3 + 1              2+1

           a





                                          7+3+1

           b









           c










           d



        2  Will the  patterns always end  in  the same  way?
