LCM/ HCF - LCM is the Lowest common factor and HCF is the highest common factor. Only when you have learnt factors and multiples, will you be able to what number factors are, and how these numbers can be divided into it. Learning LCM and HCF is not that tricky when your other bases are clear, as these bases will help you solve through LCM and HCF easily. Which is why we are offering the basic LCM and HCF factors revision before moving on to actual LCM and HCF solving. With our easy to learn techniques you will be able to learn how to find the lowest common factor, and the highest common factor. Here we will teach children to go from the basics to pro with the help of basic multiplication, tables, and division. As once the child is clear on these aspects, he/ she will have no problem solving an LCM and HFC.
