There are 15 possible triples of three positive integers whose product is 16.
According to this question, we must find the quantity of all <em>possible</em> triples such that they have a product of 16. By factor decomposition, we have that 16 is equal to the following product of <em>prime</em> numbers:

There are the following triples considering order of factors:
