The LCM, or "lowest common multiple" of two numbers is the smallest number that appears in both numbers' times tables.

For example, if we are trying to find the LCM of 6 and 8, we can look at both of their times tables:

6: 6, 12, 18, 24, 30, 36

8: 8, 16, 24, 32, 40

We see that the first number to appear in both is 24, so 24 is the LCM of 6 and 8.

LCM is the Least Common Multiple. It is the smallest possible positive number that is the multiple of two or more numbers.

LCM is an abbreviated term for "Lowest Common Multiple" and it is defined as the smallest multiple that two or more number have in common.


For example:


Multiples of 2: 2, 4, 6, 8, 12, 14, 16, 18, 20,...


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


Here the common multiples between 2 and 3 are the numbers 6, 12, and 18. The smallest common multiple is 6. Therefore, the LCM of 2 and 3 is 6.


I hope this explanation helps

LCM is the lowest common multiple between two numbers. In other words, for two numbers x and y, the LCM of x and y is the smallest number which is greater than both x and y, and also divisible by both x and y

LCM stands for "Lowest Common Multiple", effectively it is the lowest number that occurs in multiplication tables of at least 2 other numbers. For example, the LCM of 4 and 10 is 20.

LCM is a mathematical concept used to find the smallest positive integer that is divisible by two or more given numbers.

Let's consider an example. Suppose we want to find the LCM of 4 and 6.

First, we list the multiples of each number:

Multiples of 4: 4, 8, 12, 16, 20, ...

Multiples of 6: 6, 12, 18, 24, ...

To find the LCM, we look for the smallest number that appears in both lists. In this case, the number 12 is the smallest positive integer that is divisible by both 4 and 6.

Therefore, the LCM of 4 and 6 is 12.

In maths, LCM usually means the "lowest common multiple." This is the smallest positive number that two numbers can be wholly divided into, without leaving any remainder. In other words, it is the smallest shared multiple between two numbers.


For example, take the numbers 4 and 6. The multiples of 4 are 4, 8, 12, 16, 20, and so on. The multiples of 6 are 6, 12, 18, 24, 30, and so on. We want to find the smallest number that appears in both sequences. In this case, it is 12, because 4 and 6 both divide into it evenly. No number smaller than 12 in either sequence can be wholly divided by both 4 and 6.


In reality, the LCM can be useful when analysing sequences, or trying to divide numbers, quanities, or times into intervals.

The LCM is the least common multiple. This is the same multiple of two (or more) numbers which has the smallest value.

The lowest common multiple (LCM) refers to the smallest positive integer that is a multiple of two or more given numbers.


To find the LCM:

  1. identify the multiples of each number
  2. determine the smallest multiple that is common to all the numbers.

For example, if we want to find the LCM of 4 and 6:

  1. the multiples of 4 are 4, 8, 12, 16, 20, and so on, while the multiples of 6 are 6, 12, 18, 24, and so on.
  2. The smallest multiple that is common to both numbers is 12, so the LCM of 4 and 6 is 12.

LCM stands for "Least Common Multiple". It refers to the smallest positive integer that is divisible by two or more given numbers without leaving any remainder. Finding the LCM is useful when dealing with fractions, simplifying fractions, or solving problems involving multiple quantities or time intervals. By determining the LCM, we can identify the least common denominator when adding or subtracting fractions and simplify calculations involving multiple numbers or time periods.

LCM stands for Lowest Common Multiple (you can also say Least Common Multiple). You will normally be asked what the LCM is between 2 numbers e.g. 'What is the LCM between 2 and 3?' The answer is 6.


Put simply, it's asking you what the smallest (lowest) number is that is in both the 2 and 3 times tables (so a multiple they have in common). There is no number smaller than 6 that is in both the 2 and 3 times tables, so 6 is the answer.


The LCM can be one of the numbers in the question. E.g. 'What is the LCM between 2 and 4?' The answer is 4. This is because 2x2 = 4 and 1x4 = 4.

LCM = Lowest Common Multiple


LCM of two numbers is the smallest possible number that divides both numbers


One way to calculate the LCM is to list the multiples of both numbers, identify the common multiples, and then deduce the lowest common multiple.


Another way (better way) is to break down the number into its prime factors (prime factorisation) and multiply the distinct factors together to calculate the LCM.

Alexander Seaman

It is the lowest common number that two separate numbers share in their times tables. Fist you need to separate the two numbers into their prime factors. Then you multiply together the common prime factor(s) with the highest power and the prime factors that are not common. The answer will be the LCM of your two numbers.

Lowest common multiple shared within a set of numbers for example, the lowest common multiple of 6 and 3 is 6. This is because 6 is within both the 3 and 6 times tables.
