Algorithm for second problem:

the problem can be made simple by interpreting it in a different perspective.
Consider a, b, c as there different boxes. U have 4 red ball (red is the divisor 2 in the product), 5 green balls (green is 3) and 3 blue balls(blue is 5).

Now the problem is to place these 12 balls in 3 boxes, so that each box is filled with atleast one ball. Once again principle of inclusion and exclusion... So, the problem is same as the previous one..
