Prime DNA Splicer: HCF Versus LCM

  • Jun 13
  • 2 min read

The Mission:

Step into the science lab to build the Highest Common Factor (HCF) and Lowest Common Multiple (LCM) monsters using prime DNA gene blocks!


Math Skills:

  • HCF & LCM Rules: Understanding the difference between Highest Common Factor and Lowest Common Multiple.

  • Prime Factorization: Using prime numbers and indices to build complex values.

  • Intersection vs. Union: Learning that HCF takes the lowest common powers, while LCM takes the highest powers of all factors.


How to Play:

  1. Look at the prime genes (DNA blocks) provided for two different monster numbers at the top.

  2. Drag the correct prime gene blocks into the HCF Lab or LCM Lab trays based on mathematical rules.

  3. If you make a mistake, a warning speech bubble (like "Too greedy!") will appear to give you a Tip!

  4. Once you have built both correctly, click the red Verify button. If you win, click Next to tackle harder numbers!

質數 DNA 基因拼接: 對決


任務簡介:

踏入科學實驗室，使用質數 DNA 基因塊來打造「最大公因數」(HCF) 和「最小公倍數」(LCM) 怪獸！


數學技能:

  • HCF 與 LCM 規則: 理解最大公因數和最小公倍數之間的差異。

  • 質因數分解: 使用質數和指數來建構複雜的數值。

  • 交集與聯集: 學習 HCF 取最低次方的公因數，而 LCM 則取所有因數的最高次方。


玩法說明:

  1. 觀察頂部為兩隻不同怪獸數字提供的質數基因（DNA 塊）。

  2. 根據數學規則，將正確的質數基因塊拖放到 HCF 實驗室或 LCM 實驗室的托盤中。

  3. 如果你弄錯了，會出現一個警告對話框（例如：「太貪心了！」）來給你 提示 (Tip)！

  4. 當你正確完成兩者的建構後，點擊紅色的 「驗證」(Verify) 按鈕。如果成功通關，點擊 「下一題」(Next) 來挑戰更難的數字！
