What is LCM

LCM is the Lowest Common Multiple of 2 numbers. That means the lowest number that appears in both their times tables.

Some examples - what's the LCM of 2 and 3? Well, 6 is in BOTH the 2x table (2x3) and 3x table. (3x2)

Whats the LCM of 8 and 12? 24 is in both the 8x table (8x3) and the 12x table (12x2).

I'd work it out by writing down the 1st 5 numbers in both times tables (that's usually enough) and circling the numbers they both share. The lowest of the numbers you circle = the LCM.

LCM stands for Lowest Common Multiple. This consists of finding a common number multiplied a certain times for two numbers.

LCM stands for Lowest Common Multiple.

Let's say you have two numbers (n1,n2) and you want to find out what is the lowest number (LCM) which is multiple of both of our numbers (n1,n2). This smallest number is called LCM of our numbers (n1,n2).

For e.g.,

Suppose our two numbers are 10 and 15.

Method to get LCM:

Step 1: Get prime factors of your numbers.

Factors of 10 are : 2,5

Factors of 15 are: 3,5

Step 2: Multiply all the prime factors. (NOTE: Do not repeat any prime factor if it has already been considered).

LCM= 2*3*5 (NOTE: 5 was only considered once and not repeated twice)

=30

LCM is the lowest common multiple of two or more numbers. You find it by going through the multiplication table (times table) of each number. The first number that appears on the times table of each number is the LCM.

For example, the LCM of 6 and 8 is 24

Here is how I worked it out

6 x 1 = 6

6x 2 = 12

6x 3 = 18

6 x 4 = 24

6 x 5 = 30

8 x 1 = 8

8 x 2 = 16

8 x 3 = 24

LCM means LOWEST or LEAST COMMON MULTIPLE the smallest multiple that 2 or more numbers have in common. EG

intergers (numbers) 2 and 3

multiples of 2 are 2, 4,6 8,10, 12, 14, 16,18

multiples of 3 are 3.6.9.12.15.18

6, 12, 18 are common (the same) in the multiples of 2 and 3

6 is the smallest /least multiple

The abbreviation LCM stands for 'Least Common Multiple'. The least common multiple (LCM) of two numbers is the lowest possible number that can be divisible by both numbers. It can be calculated for two or more numbers as well. There are different methods to find the LCM of a given set of numbers. One of the quickest ways to find the LCM of two numbers is to use the prime factorization of each number and then the product of the highest powers of the common prime factors will be the LCM of those numbers.

LCM stands for the LOWEST COMMON MULTIPLE.

It means the lowest number in the timetables you are looking at.

For example, the LCM of 4 and 6 is 12 because:

4 timestable : 4, 8, 12, 16, 20, 24,28,32..

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

You can see the lowest multiple is 12. You can probably see 24 in both too. 24 is simply a multiple of 4 and 6, not the lowest common multiple.

Hope that helps :)

LCM stands for "Least/Lowest Common Multiple". It is the smallest positive integer that is a multiple of two or more integers added together. We can find out the common multiples of two or more numbers using different methods, eg, listing method, Prime Factorisation Method

LCM is Lowest Common Multiple.

For example among the numbers 4 , 8 , 16 what's the LCM?

The answer is 4 as it is lowest multiple to the given three numbers.

least common multiple

LCM stands for Least Common Multiple. In the question, usually they give you two or three values and ask to find the least common multiple (LCM). The easiest way to find the answer is to list the multiples of the values and once a common multiple is found, bam, well you got the answer.

for example, question asks you, "Find the LCM of 24 & 18".

List the multiples of 24 and 18 like below

24 -> 48, 72, 96

18 -> 36, 54, 72

The answer is 72 as it is the smallest multiple (or least common multiple) for both values.

LCM, or Least Common Multiple, is the smallest positive number that is a multiple of two or more numbers. In other words, it's the smallest number that all the given numbers divide into evenly.

Detailed Explanation:

1.Multiples: A multiple of a number is the result of multiplying that number by an integer. For example, the multiples of 4 are 4, 8, 12, 16, and so on.

2. Finding the LCM:

  -List Method: List the multiples of each number until you find the smallest multiple they have in common.

   - Example: For 4 and 6:

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

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

    - The LCM is 12, as it’s the first common multiple.

LCM stands for Least Common Multiple. It is the smallest number that is a multiple of two or more numbers. 

To find the LCM of two numbers, follow these steps:

List the Multiples: Write down the multiples of each number until you find a common one.

Identify the Smallest Common Multiple: Look for the smallest number that appears in both lists.

Example: Finding the LCM of 4 and 5

Multiples of 4:

• 4, 8, 12, 16, 20, 24, 28, 32, ...

Multiples of 5:

• 5, 10, 15, 20, 25, 30, 35, ...

Common Multiples:

• Both lists contain 20.

LCM:

• The smallest common multiple is 20.

LCM stands for Least Common Multiple. It's the smallest multiple that two or more numbers have in common. For example, the LCM of 4 and 6 is 12 because it's the smallest number that both 4 and 6 can divide evenly into.

LCM stands for the Lowest Common Multiple. A multiple is the times tables of a number e.g multiples of 6 are: 6, 12, 18, 24.... . If you want the lowest common multiple of two numbers you list the multiples of each number and then find the lowest one they have in common.
