Division Method


               In  this  method,  we  explore  the  number  which  divides the  given  number
               completely, i.e., without remainder.


               Let us find the factors of 16.


                              16 ÷ 1 = 16

                              16 ÷ 2 = 8
                              16 ÷ 3 = ?

                              16 ÷ 4  = 4                      Cannot divide completely.

                              16 ÷ 5 = ?

               \ 1, 2, 4, 8 and 16 are the factors of 16.


               Now, let us see some more examples.


               Example 1:  Is 6 a factor of:

                                    (a)  10      (b)  18      (c)  30?


                                                 1
                                            )
               Solution:            (a)  610

                                              −  6
                                                         Here, the remainder is 4.
                                                4      So, 6 is not a factor of 10.


                                                  3
                                            )
                                    (b) 6       18

                                              − 18
                                                         Here, the remainder is 0, i.e., no remainder.
                                                 0     So, 6 is a factor of 18.



                                                  5
                                            )
                                    (c) 6       30

                                              −  30
                                                         As 6 divides 30 exactly, so, 6 is a factor of
                                                 0     30.
