# Practice with Multiples

The *multiples* of
$\,2\,$ are $\,2\,$, $\,4\,$, $\,6\,$, $\,8\,$, $\,10\,$, $\,12\,$, $\,14\,$, $\,16\,$, $\,18\,$, and so on.

Notice that the multiples of $\,2\,$ are obtained by taking the number $\,2\,$, and multiplying successively by $\,1\,$, $\,2\,$, $\,3\,$, $\,\ldots\,$ Notice also that $\,2\,$ goes into each of these numbers evenly.

The *multiples* of
$\,3\,$ are $\,3\,$, $\,6\,$, $\,9\,$, $\,12\,$, $\,15\,$, $\,18\,$, $\,21\,$, $\,24\,$, $\,27\,$, and so on.

Notice that the multiples of $\,3\,$ are obtained by taking the number $\,3\,$, and multiplying successively by $\,1\,$, $\,2\,$, $\,3\,$, $\,\ldots\,$ Notice also that $\,3\,$ goes into each of these numbers evenly.

In general, the multiples of a number $\,\,x\,\,$ are $\,\,x\,$, $\,\,2x\,$, $\,\,3x\,$, $\,\,4x\,$, and so on. To test if something is a multiple of $\,\,x\,$, just see if $\,\,x\,\,$ goes into it evenly.
