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 stands for "Least Common Multiple." In mathematics, it refers to 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 divide evenly into. Hope this helps !

The lowest quantity that is a multiple of two or more given quantities e.g. 12 is the LCM of 2, 3 and 4

Least Common Multiple. The least common multiple of 2 numbers is the smallest number that is a multiple of both. For example : LCM of 2 and 7 is 14.

LCM stands for "Least Common Multiple." It helps us find the smallest number, that is a multiple of two or more other numbers. Let's use some examples:


Example 1: Let's say you have two numbers, 4 and 6. We want to find the LCM of these two numbers.


First, we list the multiples of each number:

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

- Multiples of 6: 6, 12, 18, 24, 30, ...


Now, we look for the smallest number that appears in both lists. In this case, 12 is the smallest number that is a multiple of both 4 and 6. So, the LCM of 4 and 6 is 12.


Example 2: Let's try three numbers this time: 3, 5, and 7.


First, we list the multiples of each number:

- Multiples of 3: 3, 6, 9, 12, 15, ...

- Multiples of 5: 5, 10, 15, 20, 25, ...

- Multiples of 7: 7, 14, 21, 28, 35, ...


Now, we look for the smallest number that appears in all three lists. In this case, 15 is the smallest number that is a multiple of 3, 5, and 7. So, the LCM of 3, 5, and 7 is 15.


The LCM helps us when we need to do things like adding or subtracting fractions with different denominators or solving problems involving multiple numbers.

Lowest common multiple. It's essentially the smallest number that is a multiple of 2 or more numbers. So for example, the smallest number that is a multiple of both 3 and 13 is 39.

Lowest common multiple! It is the lowest number that two different numbers can fit into exactly. You can find the LCM of two numbers by listing out their multiples and checking the lowest number that they both fit into.


You can also use a factor tree to find all of the two number's prime factors. You can then multiply all these prime factors together, but make sure to only include pairs of factors once!

Least Common multiple in two numbers

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.

The abbreviation LCM refers to 'Least Common Multiple' or the Lowest Common Multipl.The least common multiple (LCM) of two numbers is the lowest possible number that can be divisible by both numbers.
