Question

In a school library, there are 780 books of English and 364 books of Science. Ms. Yakang, the librarian of the school, wants to store these books in shelves such that each shelf should have the same number of books of each subject. What should be the minimum number of books on each shelf?

Answer 1

Answer:

52

Step-by-step explanation:

Number of books of English = 780 Number of books of Science = 364 780 = 2 × 2 × 3 × 5 × 13 364 = 2 × 2 × 7 × 13 ∴  The HCF of 780 and 364 = 2 × 2 × 13 = 52

Answer 2

Answer:

1

Step-by-step explanation:

It has asked minimum number of books per shelves and hasn't mentioned the limit of number of shelves so the most logical answer would be 1 book per shelf.... please any criticism is appreciated because if any logic is not opposed it would never be a good one. It has asked LCF not HCF, and LCF of any group of numbers is 1.(LCF= Lowest Common Factor)
