LCM is the Lowest Common Multiplier, it refers to the smallest whole number which can be obtained by multiplying each of the numbers in question. As an example, the LCM of 12 and 15 is 60 and can be easily obtained by way of a number line, such as in this example going (12, 24, 36, 48, 60, 72, 84, etc) and (15, 30, 45, 60, 75, 90, etc) and finding the first value which is common to each.

In Mathematics, the LCM of any two is the value that is evenly divisible by the two given numbers. The full form of LCM is Least Common Multiple. It is also called the Least Common Divisor (LCD). For example, LCM (4, 5) = 20. Here, the LCM 20 is divisible by both 4 and 5 such that 4 and 5 are called the divisors of 20.


LCM is also used to add or subtract any two fractions when the denominators of the fractions are different. While performing any mathematical operations such as addition, subtraction with fractions, LCM is used to make the denominators common. This process makes the simplification process easier.

LCM stands for Lowest Common Multiple.


It’s the smallest positive number that is a multiple of two or more numbers.


For example to find the LCM of 4 and 6, we would first need to list the multiples of each.


Remember multiples of a number are just the values in that numbers times table.


Multiples of 4 are 4, 8, 12, 16, 20, 24 …. (The list continues but let’s stop here for now)

Multiples of 6 are 6, 12, 18 …


To find the LCM we are looking for the smallest number in both times tables, it must be 12.


Therefore the LCM of 4 and 6 is 12.

LCM is a abréviation in mathematics which stands for 'Lowest Common Multiple'. The simplest way to think about LCM is to understand it as the smallest common multiple of two or more numbers.

It is the lowest common multiple. For example the LCM of 2 and 5 is 10 because 10 appears in the 5 times table and the 2 times table. 20 is a common multiple but not the LCM.

LCM is the Lowest Common Multiple of a set of numbers, one way of finding this is to multiply each number by 1, 2, 3.. etc until you have the same number for each, that will be the LCM.

LCM is the lowest common multiple. For example if you want the LCM of 3 and 7, you find multiples of 3, such as 3, 6, 9, 12, 15, 18, 21, 24, 27, and multiples of 7, such as 7, 14, 21, 28. The LCM is 21 because it is the first number on both lists.

LCM is lowest common multiple. The lowest common multiple is the smallest whole number which is a multiple of both

For example the multiples of 6 are: 6,12.18.24.30. 36 42 ..........

The multiples of 5 are 5,10,15,20,25,30,35,40...........

30 is the lowest number in both so 30 is the LCM
