      <text><![CDATA[<p>To factorise a number, \(n\) into primes the best trick is to divide by the smallest prime, \(2\). If the resulting value, \(m\), is an integer then we write it as \(2 \cdot m\). If not, then we try the next largest prime, \(3\), and repeat the process until we have obtained a product of the form \[p_1 \cdot p_2 \cdot ... \cdot 1, \] where p are prime numbers. In this particular example: \[ {@n@} = {@ta@}. \]</p>]]></text>
