720%2F2=360%2F2=180%2F2=90%2F2=45
Since 45 is not divisible by 2, then you stop.
720=2%5E4%2A45
Now continue with 45 and division by 3.
45%2F3=15%2F3=5
Since 5 is not divisible by 3, then you stop.
720=2%5E4%2A3%5E2%2A5
Now continue with 5, although it's obvious.
5%2F5=1
+720=2%5E4%2A3%5E2%2A5%5E1+
