Question

Find first three common multiples of $2,5$ and $6$.

Answer 1

Find multiples of $2,5$ and $6$:

The multiples of $2$ are: $$\begin{gathered} 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60, \\ 62,64,66,68,70,72,74,76,78,80,82,84,86,88,90... \end{gathered}$$

The multiples of $5$ are: $5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90....$

The multiples of $6$ are: $6,12,18,24,30,36,42,48,54,60,66,72,78,84,90....$

The first three common multiples of $2,5$ and $6$ are $30,60,90$.

Therefore, the common multiples have been determined.
