The Highest Common Factor (HCF) and the Lowest Common Multiple (LCM) are easy once you get used to the names.

• HCF of 8 and 12 is 4. The HCF is smaller than the numbers.
• LCM of 8 and 12 is 24. The LCM is larger than the numbers.

We decided one way to remember this would be

• Factors are feeble
• Multiples are massive.

But remember that a number is also a factor of itself and a multiple of itself.

Follow this link for a page with notes and interactive exercises :: you can try to answer the questions as you go along and then check your answers. This page explains both the ‘common sense’ method and the ‘prime factors’ method.

Any problems (or if you like this kind of exercise) just ask a question or leave a note using the ‘Ask a question about this item’ link below

Follow this link and a Web page containing BODMAS questions will open in a new window.

The questions are multiple choice questions. A question such as ‘Work out 4 + 2 x 5′ is followed by four possible answers. You click on the answer you think is correct and the Web page will check your answer! If you get one wrong, read the hints and try again.
