Question

Write the first five common multiples of $2$ and $4$.

Answer 1

Write the multiples of $2$ and $4$ and circle the common multiples.

Multiples of $2$ are: $2,\overline{)4},6,\overline{)8},10,\overline{)12},14,\overline{)16},18,\overline{)20}$.

Multiples of $4$ are: $\overline{)4},\overline{)8},\overline{)12},\overline{)16},\overline{)20},24,28,32,36,40$.

Hence, the $\overline{)4},\overline{)8},\overline{)12},\overline{)16}$ and $\overline{)20}$ are the first five common multiples of $2$ and $4$.
