Question

A library buys 36 English books, 48 Science books and 72 Mathematics books. The thickness of each book is the same. Now, the librarian wants the books to be placed in stacks, such that each stack has books of the same subject, and the height of each stack is the same. Also, the librarian wants as few stacks as possible. How many stacks of books will there be?

Answer 1

Answer:

12

Step-by-step explanation:

First, find the HCF/GCF of 36, 48, and 72. The HCF is 12. So, there will be 12 stacks of books. This is a simple example of HCF. Please mark me as brainliest. Thanks

Answer 2

Answer:

13

Step-by-step explanation:

The GCF of 36, 48, and 72 is 12 so there will be 36 / 12 = 3 stacks of English books, 48 / 12 = 4 stacks of science books and 72 / 12 = 6 stacks of math books for a total of 3 + 4 + 6 = 13 stacks.
