Explicație pas cu pas:

$\bf 36~\big|~2\\18~\big|~2\\~~~9~\big|~3\\~~~3~\big|~3\\~~~1~\big|~1$  ⇒ 36 = 2² × 3²

$\bf 80~\big|~2\\40~\big|~2\\~20~\big|~2\\~10~\big|~2\\~~~5~\big|~5\\~~~1~\big|~1$  ⇒ 80 = 2⁴ × 5

$\bf100~\big|~2\\~~~50~\big|~2\\~~~25~\big|~5\\~~~~~5~\big|~5\\~~~~~1~\big|~1$  ⇒ 100 = 2² × 5²

$\bf 136~\big|~2\\~~~68~\big|~2\\~~~34~\big|~2\\~~~17~\big|~17\\~~~~~1~\big|~1$  ⇒ 136 = 2³ × 17

$\bf 240~\big|~2\\~120~\big|~2\\~~~60~\big|~2\\~~~30~\big|~2\\~~~15~\big|~3\\~~~~~5~\big|~5\\~~~~~1~\big|~1$   ⇒ 240 = 2⁴ × 3 × 5
