Description

Have you ever wondered what the divisibility rules are? Want to know how to find the HCF and LCM of numbers? Do you know that HCF stands for Highest Common Factor and LCM stands for Lowest Common Multiple? Want to know how to do Prime Factorisation using Factor Trees? Then this video will answer all those questions you may - or may not! - have. Lots of worked examples are provided with downloadable notes (at www.maffsguru.com).
