How to work with Factors and Multiples
As today is the NSPCC’s Number Day 2022, before learning about factors and multiples, why not learn some amazing facts about numbers!
- In Old Norse, hundrath actually means 120, not 100
- There is no symbol for zeros in Roman numerals, whilst the ancient Greeks didn’t consider zero to even be a number! Apparently Aristotle decided as you could not divide by zero, then it was not a number!
- Scientists have shown that bees can count up to four, and recognise the concept of zero. They were actually trained to choose which samples had “more” or “less”. Amazing!!
- The only number which has the same number of letters, as the value it depicts, is the number four!
- There is a Guinness World Record for counting to one million. Jeremy, from Alabama, spent 16 hours per day counting aloud. Surely learning all about factors and multiples would be a better use of time!
“How to work with Factors and Multiples” explains what factors, prime factors and multiples are. It includes explanations of how to find factors and multiples, and how to complete a Prime Factor Tree. Included, as always, are questions to try, and answers to check your understanding.
