LCM refers to least common multiple. For example if there are two numbers, 12 and 9 then multiples of 12 are 12*1, 12*2, 12*3 so 12, 24, 36 and so on and similarly multiples of 9 are 9, 18, 27, 36... LCM will be 36 because it is a multiple of both of these numbers and it is the smallest multiple that is common between both 12 and 9.

LCM stands for Lowest Common Multiple and refers the lowest number that can be divided by two other numbers. For example:


What is the LCM of 3 and 4?

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27,...

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44,...


Through observation both 12 and 24 are multiples of 3 and 4.


Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27,...

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36,...


Since 12 is the lowest value, 12 is the LCM of 3 and 4.


What is the LCM of 270 and 252

If you have covered finding the product of prime factors you may use this method to find the LCM of two numbers.


270=2x3x3x3x5

252=2x2x3x3x7


The LCM is the product of the lowest values shared between the product of prime factors.


270=2x3x3x3x5

252=2x2x3x3x7


So LCM=2x3x3

LCM=18

LCM is the short form of Least Common Multiple ,the least common multiple is defined as the smallest multiple that two or more numbers have in commom example

take 2 and 3

2 multiples 2 4 6 8 10 12 14 16 18 20

3 multiple 3 6 9 12 15 18 21 24 27 30

here common multiples are 6 12 18

LCM stands for the Lowest common multiple.

  • all this means is a number which is the smallest multiple that 2 different numbers have in common

for example the LCM of 2 and 3 is...

2,4,6,8,10

3,6,9,12

so the answer would be 6

LCM stands for the Lowest Common Multiple. It means the smallest multiple of 2 or more numbers. For example the LCM of 6 and 4 would be 12 as its the smallest number that appears in both times tables.

LCM stands for Lowest common multiple. it is the smallest number that is a multiple of two or more numbers - for example - Let us take two numbers, 2 and 5. Each will have its own set of multiples.

  • multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, …
  • multiples of 5 are 5, 10, 15, 20, …


the Lowest common multiple here is 10!

Hi Iftikhar,


The lowest common multiple (LCM), is the lowest multiple that is found in both numbers you are given.


for example: the LCM of 3 and 12

You would simply start to state all the multiple of 3 and 12 until you reach a common number.


3 ==> 3,6,9,12,15

12 ==> 12,24


As you can see, the lowest common multiple which is found in both numbers is 12.


Hope that helps!


Kindest regards
