    $\dfrac{4 × 15 × 9 × 24}{3 × 12 × 8 × 5}$

    `= `$\dfrac{2 × 2 × 3 × 5 × 3 × 3 × 2 × 2 × 2 × 3}{3 × 2 × 2 × 3 × 2 × 2 × 2 × 5}$

    `= `$\dfrac{3 × 3}{1}$

    `= 9.`

    $\dfrac{4 × 15 × 9 × 24}{3 × 12 × 8 × 5}$

    `⇔` $\dfrac{4 × 5 × 3 × 3 × 3 × 8 × 3}{3 × 4 × 3 × 8 × 5}$

    `⇔` `3 × 3`

    `= 9`
