Question

Take the multiples of $2$ and $8$. The greatest three common multiples from the grid are :

• A. $32,40,48$
• B. $8,16,24$
• C. $2,4,6$
• D. $16,24,40$

Answer 1

Answer: (A)

$32,40,48$

We know that a multiple of a number is that number multiplied by an integer. Integers are negative as well as positive.

Now, we write the multiples of $2$ and $8$ are as follows:

Multiples of $2$ are $-2,-4,-6,-8,-\mathrm{10.....},2,4,6,8,10,.......$

Multiples of $8$ are $-8,-16,-24,-32,-\mathrm{40.....},8,16,24,32,40,.......$

Now, from the given grid of numbers, the common multiples of $2$ and $8$ are $32,40,48$ because all of these numbers are divided by both $2$ and $8$.

Hence, the common multiples of $2$ and $8$ are $32,40,48$.
