Prompt 6: Prime Factorization

  1. Do you use prime factorisation for any of these topics? If not, is this a result of sequencing of topics? Would you consider teaching prime factorisation earlier?
  2. Are there any other applications of prime factorisation? (excluding the obvious HCF and LCM)
  3. How do you initially teach prime factorization? Factor trees?
  4. An interesting avenue for prime factorization:

5. When is multiplication of numbers easier using prime factorization? When isn’t it?
6. In cell 3, why does this algorithm work for finding how many factors a number has?
