LCMsThe Lowest Common Multiple (LCM) is the smallest positive number that is a multiple of two or more numbers.

For example the LCM of 4 and 6 is 12 because

Multiples of 4 are 4, 8, 12, 16, 20….

Multiples of 6 are 6, 12, 18, 24…

12 is the first number in both lists.

Here is a great phone app that will help you with your arithmetic so you don’t need to be afraid when you are faced with that non-calculator exam. It’s called Maths Tricks and shows you lots of short cuts to performing calculations and gives you endless practice to improve your speed and accuracy. Best of all it’s free!

You can find it on Google Play. I am recommending this because it is good, not because I have any connection to the app.
