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:

16 = 2^{4}

There are the following triples considering order of factors:

(i) \{16, 1, 1\}, (ii) \{1, 16, 1\}, (iii) \{1, 1, 16\}, (iv) \{2, 8, 1\}, (v) \{8, 2, 1\}, (vi) \{8, 1, 2\}, (vii) \{2, 1, 8\}, (viii) \{1, 2, 8\}, (ix) \{1, 8, 2\}, (x) \{1,4,4\}, (xi) \{4, 1, 4\}, (xii) \{4,4,1\}, (xiii) \{2,2,4\}, (xiv) \{2, 4, 2\}, (xv) \{4,2,2\}

There are 15 possible triples of three positive integers whose product is 16.

X represents the number of books you have. If you say to a friend "I have more than 25 books" then you can write "x > 25" which says "x is greater than 25"

Something like x = 50 will make x > 25 since 50 is larger than 25. In contrast, a value like x = 20 is going to make x > 25 false because 20 > 25 is false (20 is smaller than 25, not larger)
