The first number larger than 300 that is a multiple of both 6 and 8.

Question

Take a look at the question No. 23 on Page-42.

Column A                                                  Column B
----------------------------------------------------------------------
The first number larger than                                 324
300 that is a multiple of both 6                           
and 8.

The given answer is (B). I.e. Column A < Column B

How is that a correct answer?

To my understanding, since, the first number larger than 300 that is a multiple of both 6 and 8 is 324, the answer should be (C). I.e. Column A == Column B.

So, what is going on here?

Answer 1

The least common multiple of $6$ and $8$ is $24$, so the smallest number greater than $300$ that is a multiple of $24$ is $24 \cdot 13 = 312$.

Answer 2

$6$ and $8$ divide $312$. $\text{ }$

Answer 3

Note that $324$ is not divisible by $8$, then try with $306$, $312$ and $318$.
