To start understanding on LCM, we first need to know what multiples are.
We first explore Multiples of 2. They are 2,4,6,8,10,12,14, ……….
Multiples of 3 are 3,6,9,12,15,18,21,24,27,30, ……….. .
Multiples of 4 are 4,8,12,16,20,24,28,32,36,40, ………
Here we look at finding the LCM of 2 numbers. Let us say that we need to find the LCM of 2 and 3
Multiples of 2 are 2,4,6,8,10,12,14,16,18,20,24 ……….
Multiples of 3 are 3,6,9,12,15,18,21,24,27,30, ………..
The next step is to identify the common multiples, i.e. similar numbers in the list of multiples of 2 and multiples of 3.
They are 6,12,18,24,…………
LCM is the smallest number in the common multiple list, i.e. 6
At Just-Math, we have specially prepared learning programs to help children master each and every important areas in mathematics. Our worksheets are all specially designed to ease the learning of mathematics. When a child enrols for our classes, we will conduct a simple assessment to gauge the present math ability of the child. Based on this assessment, we will be able to determine the suitable level to commence your child’s learning journey.
Your child’s progress will be monitored closely to suitably advance them in their learning of new areas as and when suitable. Your child should progress smoothly given the regular exercise given to them.
Go to our main page for more information regarding this special math program. Students as young as 4 years old can start learning using this special program.
