Solution

Total number of English books = 336
Total number of mathematics books = 240
Total number of science books = 96
∴ Number of books stored in each stack = HCF (336, 240, 96)
Prime factorization:
336 = 24 × 3 × 7
240 = 24 × 3 × 5
96 = 25 × 3 
∴ HCF = Product of the smallest power of each common prime factor involved in the numbers = 24 × 3 = 48 
Hence, we made stacks of 48 books each.
∴ Number of stacks ` = 336/48 + 240/48 + 96/48 = ( 7 +5 + 2) = 14`
