It is the least common multiple, also known as the lowest common multiple of two (or more) integers a and b, is the smallest positive integer that is divisible by both.


To calculate the LCM of the two numbers A and B by the listing method, we use the steps given below:

  • Step 1: List the first few multiples of A and B.
  • Step 2: Mark the common multiples from the multiples of both numbers.
  • Step 3: Select the smallest common multiple. That lowest common multiple is the LCM of the two numbers.

Take a set of numbers. The number which is a multiple of all numbers involved is a common multiple. The lowest common multiple is thus the lowest possible version of this. For example, common multiples of "4, 2, 7" are: 28, 56, 84. The lowest of these numbers is 28, so 28 is the lowest common multiple.

Lowest Common Multiple - this means that if you have two numbers, you need to find the lowest number that is a multiple of each one!

LCM is the lowest common multiple. To find the LCM of two numbers, you need to find the multiples of each number. Then, find the smallest multiple that is divisible by each number.


For example:


5 and 8

5: 5, 10, 15, 20, 25, 30, 35, 40

8: 8, 16, 24, 32, 40


So 40 is the lowest common multiple (LCM) of 5 and 8

LCM stands for 'Lowest Common Multiple' i.e. a number that is a multiple of two other numbers and also the lowest common multiple between them e.g. the LCM of 4 and 6 is 12, the LCM of 8 and 12 is 24

LCM is the method to find the smallest possible multiple of two or more numbers. LCM stands for Least common multiple. LCM of two numbers is divisible by both numbers. For example, the LCM of 6 and 8 is 24. Hence 24 is divisible by both 6 and 8.

LCM; Least common multiple.


It is the multiple of two other numbers. It can be used to find a common denominator of two fractions

Multiples of 3; 3,6,9,12,15,18,21,24,27,30

Multiples of 5; 5, 10, 15,20, 25, 30


common multiples are 15 and 30


Hope this helps

Hi LCM is Lowest Common Multiple or Factor.


To find the LCM you need to find which multiple you will need to write the multiples of both numbers and find the common number between the two.


For example to figure out the LCM of 10 and 12.

Multiples of 10 - 10, 20 ,30,40,50,60,70

Multiples of 12 - 12,24,36,48,60.

60 is the first common multiple so the LCM of 10 and 12 is 60.


I hope this helps :)
