Well there are many ways to do it. This is just one. This might look weird but oh well.

720

/\

72 10

/\ /\

12 6 5 2

/\ /\

3 4 3 2

/\

2 2

So it breaks down into 72x10. Then 72 breaks into 12x 6 while 10 breaks to 5x2. Then 12 breaks into 3x4. 6 breaks into 3x2. 5 and 2 stay the same. Then 4 breaks into 2x2.
