1 | Timestamp | Score | Q23 | Question 24 | Question 25 | Question 28 | Question 29 | Question 35 | Describe clearly, how you decide which method (HCF or LCM) to apply in order to solve the problem. | Name | Reg no. | Group | |

2 | 1/20/2017 19:50:55 | 4 / 5 | HCF | LCM | HCF | LCM | LCM | HCF | If the question is asking for how many objects can be equally distributed, HCF is used to solve it. If the question asks for at which moment do the objects clash, LCM is used to solve it. | Christabel Lee | 1 | 1 | |

3 | 1/21/2017 23:20:06 | 4 / 5 | HCF | LCM | HCF | LCM | LCM | HCF and LCM | Think about how I would solve the problem and from there i can tell which method my answer would be. | Foo Lin Hui | 2 | 3 | |

4 | 1/20/2017 11:21:10 | 4 / 5 | HCF | LCM | HCF | LCM | LCM | HCF and LCM | If the question asks or needs to find the largest possible common number that all the numbers have, I will decide to use HCF. If the question needs or asks for the lowest possible number that all the numbers can multiply by another number to obtain it, I will use LCM. | Sofia Pineda Radivojevic | 3 | 3 | |

5 | 1/20/2017 15:16:53 | 4 / 5 | HCF | LCM | HCF | Both HCF and LCM | HCF | HCF and LCM | If the question is about dividing things into equal lengths, I would put it as HCF. If it is about how things will meet together, I would put it as LCM. | Annie | 4 | 1 | |

6 | 1/20/2017 11:35:52 | 3 / 5 | HCF | LCM | HCF | Both HCF and LCM | LCM | HCF and LCM | I check whether the main method is to multiply or to divide, if its multiply then I have to find the LCM and if its divide then its HCF | Simran Sharma | 5 | 3 | |

7 | 1/20/2017 11:21:01 | 2 / 5 | HCF | LCM | Both HCF and LCM | Both HCF and LCM | LCM | HCF | If the question is asking for the greatest number then it is HCF but if the question is asking for division then it is LCM | Woo Syn Ting Sara | 6 | 2 | |

8 | 1/20/2017 11:18:31 | 4 / 5 | HCF | LCM | Both HCF and LCM | LCM | HCF | HCF | i will see whether the number needs me to find the shortest or longest of something or a duration | HAO MIN | 7 | 4 | |

9 | 1/20/2017 11:16:43 | 4 / 5 | HCF | LCM | HCF | LCM | LCM | HCF | If they ask for highest possible, it is HCF, but if they ask for when they meet again, it is LCM | Corwin Chong Yao Kiat | 8 | 4 | |

10 | 1/20/2017 11:22:27 | 3 / 5 | HCF | LCM | HCF | Both HCF and LCM | LCM | HCF and LCM | HCF is a method when the numbers have to be divided to until the numbers are the same. LCM is a method when the numbers have to be multiplied until all the numbers are the same. | Hafiz Sadali | 9 | 3 | |

11 | 1/19/2017 20:12:40 | 4 / 5 | Both HCF and LCM | LCM | HCF | LCM | HCF | HCF and LCM | I will first see if they ask mostly towards a factor or more of multiplication | Ho Rui Yang | 10 | 2 | |

12 | 1/20/2017 11:19:37 | 2 / 5 | LCM | LCM | Both HCF and LCM | Both HCF and LCM | HCF | HCF and LCM | Read the context of the question and think of how to solve it, then match it to HCF/LCM | Jia Zeyu | 11 | 4 | |

13 | 1/19/2017 14:39:54 | 3 / 5 | HCF | LCM | HCF | Both HCF and LCM | LCM | HCF and LCM | I read the question, analyse it and then deduce the answer. | Joel Chew | 12 | 2 | |

14 | 1/20/2017 11:17:40 | 3 / 5 | HCF | LCM | Both HCF and LCM | LCM | Both HCF and LCM | HCF | I check which question needs to use the final answer divided by the original numbers (LCM), or the original numbers divided by the final answer (HCF) | Ethan Loke Ji Han | 13 | 1 | |

15 | 1/20/2017 11:19:55 | 5 / 5 | HCF | LCM | HCF | LCM | HCF | HCF and LCM | I see if whether the question is finding . For example, if they are finding when three runners meet again, I find Lcm | Lucas Lim | 15 | 1 | |

16 | 1/20/2017 11:19:41 | 3 / 5 | HCF | LCM | HCF | Both HCF and LCM | LCM | HCF | In the question, we must find what the question is looking for. If it is looking for the most number of ?, then it is HCF. If it is looking for when the number will meet again, then it is LCM. | Mohamad Zuhairi Bin Zainudin | 17 | 2 | |

17 | 1/20/2017 11:19:20 | 3 / 5 | HCF | LCM | HCF | Both HCF and LCM | LCM | HCF and LCM | I needed to see if the problem was like a few of the lcm questions i did before | Muhammad Adam Aqasha Bin Mohamed Hisham | 18 | 2 | |

18 | 1/19/2017 19:43:55 | 4 / 5 | HCF | LCM | Both HCF and LCM | LCM | HCF | HCF and LCM | Check what the questions specifically ask you to find. | Norman Bin Hamdan | 20 | 2 | |

19 | 1/20/2017 22:32:32 | 2 / 5 | Both HCF and LCM | LCM | LCM | LCM | LCM | HCF and LCM | See what specific value does the question ask for. Some questions require us to find the HCF or LCM or both value the equate the answer. | Norman Bin Hamdan | 20 | 2 | |

20 | 1/20/2017 11:16:38 | 3 / 5 | HCF | LCM | Both HCF and LCM | Both HCF and LCM | HCF | HCF and LCM | use lcm when there is a need to find multiples | Qin Guan | 21 | 2 | |

21 | 1/20/2017 11:18:23 | 3 / 5 | HCF | LCM | HCF | Both HCF and LCM | LCM | HCF and LCM | I would see whether the question is asking for HCF or LCM. | Richard Kok Zen Xian | 22 | 2 | |

22 | 1/20/2017 11:20:41 | 2 / 5 | LCM | LCM | Both HCF and LCM | Both HCF and LCM | HCF | HCF and LCM | Look carefully at the question and decide whether to use HCF or LCM. | Matthew Tan | 23 | 4 | |

23 | 1/20/2017 19:14:33 | 3 / 5 | Both HCF and LCM | LCM | HCF | LCM | LCM | HCF and LCM | I use HCF if the question needs us to divide some numbers. I use LCM if the question requires us to to find the multiples of the numbers. | Wan Hanafi | 24 | 3 | |

24 | 1/20/2017 11:23:29 | 3 / 5 | HCF | LCM | Both HCF and LCM | LCM | Both HCF and LCM | HCF | If I need to find when a certain number of events happen at the same time, I use LCM, then if I need to find the maximum number of parts for example, I use HCF | Xee Zun Kye | 25 | 4 | |

25 | 1/23/2017 19:58:39 | 2 / 5 | Both HCF and LCM | LCM | Both HCF and LCM | LCM | LCM | HCF and LCM | when you want to find a common meeting point of the numbers, use LCM. when you want to find the value of numbers divide by a common factor, use HCF. | loke yi ming | 14 | 1 | |

26 | 1/23/2017 21:00:40 | 2 / 5 | Both HCF and LCM | LCM | Both HCF and LCM | LCM | LCM | HCF and LCM | when you want to find a common meeting point of the numbers, use LCM. when you want to find the value of numbers divide by a common factor, use HCF. | loke yi ming | 14 | 1 | |

27 | 1/24/2017 8:20:53 | 4 / 5 | HCF | LCM | HCF | LCM | LCM | HCF | When the question ask what is the highest possible answer then use HCF/ when they ask what is the time they will meet again it will be LCM | Ma Shun Ngai George | 16 | 1 | |
