Question

Write first $10$ multiples of $6$ and $8.$ Which is the smallest common multiple of both these numbers?

• A. $48$
• B. $24$
• C. $72$
• D. $30$

Answer 1

The correct option is B $24$

First ten multiples of $6$ are,

$6,12,18,24,30,36,42,48,54,60$

And, first ten multiples of $8$ are,

$8,16,24,32,40,48,56,64,72,80$

From the above given multiples of $6$ and $8$ we can observe that $24$ is the smallest number present in both. Hence, smallest common multiples of $6$ and $8$ is $24.$
