You can put this solution on YOUR website!
It has to be even and end in a 0. That will take care of 2,4,and 5.
7X3=21 and their product works for the above if it is 210.
All 5 numbers divide into 210 evenly.
Once you have the first part, you can try 70,140,210.
Alternatively, you can multiply them all together and get 840. That works, then cut it in half. 420 works, and 210 works, but 105 doesn't.
