Factorisation

Numbers may be split into component parts, such that with these components are multiplied together we get back to the original number. For example, the number 6 is made up from 2 times 3. The number 12 is made up from 2 times 6, however we may go further in this case, 6 may be broken up into 3 times 2. Therefore 12 maybe written has 2 times 2 times 3.
If we look at the example for 12 we see that it is made up from 2 times 2 times 3. These last numbers, the 2, 2, 3 are known as the factors of 12. When we realise that this then the topic of factorization is not that fearful.
This video explores how to factorise numbers, it also delves into algebra to show how algebraic expressions may also be factorised. It is done in a straightforward manner.
