What is LCM

Hi, the LCM is the Lowest Common Multiple of a set of numbers. This means it is the smallest number in which all of those numbers are factors. E.g, If we have 2, 3 and 5. The LCM is 30

LCM in mathematics stands for Least Common Multiple.

The name pretty much explains what it means, to elaborate on that;

Least: the smallest

Common: Something that is the same or similar

Multiple: Stands for any number that can is completely divisible by this number.

For example, if you want to find the LCM of numbers x,y.

You should look out for a number that smallest number that would be completely divided by both x and y ( that's is the reminder would be zero).

What is the least common multiple of 3 and 5?

Multiples of 3: 3,6,9,12,15,18

Multiples of 5: 5,10,15,20

LCM is 15.

Hope this helps,

Can you relate this to a real-life example and apply the concept of LCM to solve this?

To throw a birthday party, I need to arrange chairs with balloons attached for the guests. I went to a decorator team to find chairs available in sets of 6 and balloons available in sets of 4. Assuming there have to be no chairs without balloons or vice versa, what should be the minimum number of each of these that I should order?

LCM is the lowest common multiple. In other words, LCM is the lowest possible number that can be divisible by two numbers.

For example, if we are looking for the LCM of 2 and 5, we must find the lowest number that goes into both 5 and 2. There are many methods of finding this out but as these are both quite low numbers we can use the listing method.

We do this by writing out both multiples of 2 and 5:

2,4,6,8,10

5,10,15,20

Then we find the number that goes into both which in this case is 10.

LCM is the 'Least Common Multiple'- the smallest multiple that two or more numbers have in common.

Example: The LCM of 10 and 15,

Multiples of 10: 10, 20, 30, 40

Multiples of 15: 15, 30, 45, 60

Therefore, 30 is the LCM of 10 and 15.

Least common multiple

it stands for Lowest Common Multiple.

common multiples of 2 numbers

ex:

time-tables of 2 numbers

Multiples of 2 - 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, …

Multiples of 5 - 5, 10, 15, 20

so common multiples of 2, 5 are 10, 20

and Lowest Common Multiple -> 10

LCM is the short form for “Least Common Multiple.” The least common multiple is defined as the smallest multiple that two or more numbers have in common. For example: Take two integers, 2 and 3. Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.

LCM is the lowest common denominator.

This is when you have 2 numbers and you need to find the lowest number that is a multiple of both of those numbers.

For example, with the numbers 35 and 42, the lowest common denominator is 7. That is because this is the lowest number that BOTH 35 and 42 can be divided by to achieve a whole number.

You may think the LCM is 1, as any number can be divided by 1 to get a whole number, but 1 doesn't count as an LCM.

This is known as the least common multiple of two or more numbers. Here is an example, some multiples of 3 are: 3,6,9,12. The multiples of 2 are: 2,4,6,8 therefore the smallest common number between 3 and 2 is 6. Let me know if this helps!

The LCM is the Lowest Common Multiple. The Lowest Common Multiple of two numbers is the smallest number that is a multiple of both of them.

LCM is the least common multiple. In the case of two numbers, the least common multiple is the smallest number that is a multiple of both numbers.

LCM stands for "Least Common Multiple".

It is the smallest positive integer that is divisible by two or more given numbers without leaving any remainder.

For example, the LCM of 3 and 4 is 12. This is because 12 is the smallest number that is divisible by both 3 and 4 without leaving a remainder.

The LCM of two numbers is their lowest common multiple. It is the lowest number than can be divided by these two numbers. For example, the lowest common multiple of 2 and 8, is 8.

It stands for ‘Lowest Common Multiple’. It means, what is the lowest multiple that is common to 2 or more numbers. For example, the LCM of 6 and 8 is 24.

LCM stands for 'Lowest Common Multiple'. A multiple of a number is the answer when you multiply that number by another number. A common multiple is a multiple that is the same for different numbers. For example 4 and 6 have the some same multiples such as 12, 24, 36 etc. The lowest multiple is just the smallest multiple shared by the numbers, or the lowest number they both fit into exactly. The LCM for 4 and 6 is 12. The LCM for 5 and 10 is 10. When we talk about the multiples of numbers, the numbers must be integers or whole numbers, not fractions or decimals.
