Question
In a school there are two sections - section $A$ and section $B$ of Class $VI$. There are $32$ students in section $A$ and $36$ in section $B$. Determine the minimum number of books required for their class library so that they can be distributed equally among students of section $A$ or section $B.$

Answer

We have to find the $LCM$ of $32$ and $36$.
Prime factorization of $32 = 2 \times 2 \times 2 \times 2 \times 2$
Prime factorization of $36 = 2 \times 2 \times 3 \times 3$
Required $LCM = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3 = 288$
Therefore, Minimum number of books required $= LCM$ of $32$ and $36 = 288$ books
