Answer: [1 Mark]

A Common Multiple is a number that is a multiple of two or more numbers.
We can find all the factors of 16, as shown below.
16=1 $\times$ 16
16=2 $\times$ 8
16=4 $\times$ 4

Since the number is divisible by 16, it will also be divisible by its factor i.e. 1, 2, 4, 8, 16.
So, clearly, the number which is divisible by 16, will also be divisible by 1, 2, 4, 8.
