Key Takeaways (15 Jan)

Recall the past couple of lessons on
- Prime factorisation
- HCF
- LCM

State three key learning points as comments.

25 comments:

  1. Prime factorisation is the process of expressing a composite number as the product of prime factors.
    HCF(Highest Common Factor)is used to find the highest factor that is the same of two or more numbers
    LCM(Lowest Common Multiple)is used to find the lowest multiple that is the same of two or more numbers

  2. 1.we should use prime factorisation to find the HCF and LCM.
    2.after you have done prime factorization, you select the highest power/index from each set and multiply to get LCM.
    3.if A is bigger than B, B is the HCF of the two

  3. 1. Prime factorisation is commonly used for finding LCM.
    2. HCF is the highest factor of 2+ numbers
    3. LCM means Lowest Common Multiple of 2+ Numbers

  7. 1. Prime factorisation is an easier way to find HCFs and LCMs.
    2. Most numbers can be divided by prime numbers.
    3. 1 cannot be prime factorised.

  8. Prime factorization is one way to find HCFs
    The lowest common multiple or least common multiple is the lowest multiple two numbers have in common
    Prime Factorization is finding which prime numbers multiply together to make the original number

  9. Prime factorisation is one of the many ways to find LCM and HCF.
    The lowest common multiple is a common number between 2 or more numbers
    HCF is the highest divisible number 2 numbers can be divided with

  10. Prime Factorisation is can be used to figure out LCM and HCF
    HCF(Highest Common Factor) is the largest similar factor between 2 or more numbers. The highest possible common factor would be the smallest number.
    LCM(Lowest Common Multiple) is the smallest similar multiple between 2 or more numbers. The lowest possible common multiple is the largest number.

  11. Prime Factorisation can help to find HCF and LCM.
    HCF is the largest factor of two or more numbers which is always either smaller or equal to the smaller number.
    LCM is the lowest multiple of two or more number, which can be divided by the numbers.

  12. 1. We can use a table or a tree to find HCM and LCF
    2. Most numbers can be divided by prime numbers.
    3. 1 cannot be prime factorised

  13. We can use prime factorisation to find out the LCM or HCF of a group of numbers.
    HCF is the highest common factor of two or more numbers and the highest possible factor of any number would be itself.
    LCM is the lowest common multiple between two or more numbers.

  14. We use the prime factorisation( The table/ Tree) to find out the LCM and the HCF
    HCF is always lower or equal to one of the lower number
    LCM is the lowest common multiple of the two or more numbers

  15. We can use the table method to repeatedly divide to find either LCM or HCF.
    Prime Factorization are used to answer LCM or HCF Questions
    1 Cannot be counted a factor

  16. We can use prime factorisation to find out the HCF and LCM.
    The HCF of a number is the number itself.
    We can the LCM if there are two same numbers from two different factors.

  17. The ladder method can be used to find out the prime factors
    The prime factors can be used to find the HCF and LCM
    The HCF is always lower or equal to the number

  18. 1.The cube root and square root can be found using prime numbers
    2. 1 is cannot be count as a factor as every number has a factor of 1
    3.If X is bigger than Y , than Y is the HCF of the two numbers

  19. 1.HCF and LCM can be found using the prime factorisation method
    2.HCF is taking the smallest factors of two or more numbers
    3.LCM is taking the biggest factors of two or more numbers

  20. HCF,LCM,cube root and square root can be found using prime factorisation
    A composite is made of two of more prime numbers multiplied
    Factor tree and Prime ladder are ways you can use for prime factorisation

  22. 1) prime factors are one of the many ways to find the HCF and LCM of a number
    2)1 cannot be prime factorised
    3) HCF is the largest factor of two or more numbers which is always either smaller or equal to the smaller number of all the numbers
