In first case, **GCD** of **{3, 6}** is **3** and **LCM** of same subsequence is **6**. So, **(LCM - GCD)** is **3** here.In second case, **GCD** of **{6, 8, 12}** is **2** and **LCM** of same subsequence is **24**. So, **(LCM - GCD)** is **22** here.In third case, **GCD** of **{8, 12}** is **4** and **LCM** of same subsequence is **24**. So, **(LCM - GCD)** is **20** here.In fourth case, **GCD** of **{6, 12}** is **6** and **LCM** of same subsequence is **12**. So, **(LCM - GCD)** is **6** here.In last case, there’s no subsequence which difference of **LCM** and **GCD** equals to **10**.
