Answer 1

Step-by-step explanation:

If we want to find the smallest number to be divided by such numbers we have to find the LCM

$\begin{array}{c | l} \: 2&30,48,70 \\ \hline2&15,24,35 \\ \hline2&15,12,35 \\ \hline 2&15,6,35 \\ \hline 3&15,3,35 \\ \hline 5&5,1,35 \\ \hline 7&1,1,7 \\ \hline&1 ,1,1\end{array}$

So,

LCM = 2×2×2×2×3×5×7 = 1680
