Lowest Common Multiple. The smallest number that 2 or more numbers have in their times table e.g. 2 and 6 have 12 and 24 in common

LCM is lowest common multiple. It is the lowest number that can be divided into a set of numbers without a remainder. We use it for things like finding a common denominator when working with fractions. For example, the lowest common multiple of 2 and 5 is 10.

LCM stands for the least common multiple. The least common multiple is the smallest multiple of two or more numbers. The easiest way to visualise it is to list the multiples of the numbers.

So for instance, if we are finding the LCM of 3 and 5 we would list the multiples of each:

3 - 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

5 - 5, 10, 15, 20, 25, 30, 35, 40, 45, 50

We would then look for the smallest common number in both of the lists which is 15.

LCM stands for lowest common multiple. This means the lowest positive number that is a factor of these numbers listed. For example, if you were asked to find the LCM of 4 and 9, it would be 36.

LCM is the lowest common multiple of two or more integers. For example, the LCM of 16 and 20 will be 2x2x2x2x5=80 where 80 is the smallest common multiple.

Lowest Common Multiple (LCM) is the lowest multiple shared by 2+ numbers.


For example, the multiples of 20 are: 20, 40, 60, 80, and the multiples of 30 are: 30, 60, 90, 120.


The lowest integer that both numbers share is 60, so 60 is the LCM of 20 and 30!

The lowest common multiple (LCM) of some numbers is the lowest possible number that is divisible by all those numbers . For example the LCM of 2,3, and 5 is 30. Why? because 30 is the lowest possible number divisible by all of 2, 3 and 5.

The Lowest Common Multiple. This is when you are finding the lowest number that two numbers can go into. For example, the lowest common multiple of 6 and 3 is 12, because 6 and 3 are both factors of 12.

A LCM is the Lowest/Least Common Multiple. This is the lowest number that is a multiple and that is shared between two or more numbers.


For example, if asked what the lowest common multiple is between 3 and 10, we would need to find all the multiples of 3 and 10:


3- 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36...

10- 10, 20, 30, 40, 50...


Since 30 is the lowest number that appears in both lists, the LCM of 3 and 10 is 30.

LCM stands for Lowest Common Multiple. Given a set of numbers, what is the lowest number that is a multiple of all the numbers in the set. For example, if you are asked for the LCM of 2, 4, 6, then the answer would be 12 because 12 is the lowest number that is the multiple of all of those 3 numbers.

LCM is the lowest common multiple.

For example, if you wanted to find the LCM of 24 and 36, you would be looking for a number that is divisible by both 24 and 36.

To do this, you would first write out the first few multiples of each like this:

24, 48, 72

36, 72, 108


As you can see here, 72 appears is the first number to appear in both lists so is the LCM of 24 and 36.

LCM stands for Lowest Common Multiple.


This means when you are given two numbers, what is the lowest number in BOTH of their times tables.


For example:


If they asked you to find the Lowest common Multiple of 10 and 15, you would write their times tables out like so:


10 15

20 30

30


As you can see, both of them have 30 in their times table (30 is a multiple of both 10 and 15) which means that it is their LCM.


Hope this helps! :)
