Question 975880
You have to make a factor tree. Keep factoring until you get to a “dead end”.

                                                                             72
                                                                            /    \
                                                                           9     8
                                                                          /  \   /  \
                                                                         3   3 2  4
                                                                                    /  \
                                                                                  2    2
Now you multiply all the “dead ends” and you will get 72.

{{{highlight(72=3*3*2*2*2)}}} check: 3*3*2*2*2 9*2*2*2 9*8=72 Correct.
