You can put this solution on YOUR website! find two positive numbers whose difference is 16 and product is 420
---------
Look for a pair of factors or 420 that differ by 16
---
1*420 doesn't work
2*210 doesn't work
etc
----------
Since they differ by 16, they must both be even or both odd.
Since the product is even, they're both even numbers.
