The multiples the **3** space 3, 6, 9, 12, 15, 18, ... Etc**The multiples of 5** are 5, 10, 15, 20, 25, ... Etc

Find the first **Common** (same) value:

The **Least typical Multiple**of 3 and also 5 is **15**

(15 is a multiple of both 3 and 5, and is the smallest number like that.)

## So ... What is a "Multiple" ?

We obtain a **multiple** that a number when we **multiply the by an additional number**. Such together multiplying through 1, 2, 3, 4, 5, etc, however not zero. Just like the multiplication table. **Here room some examples: **

The multiples of 4 are: 4,8,12,16,20,24,28,32,36,40,44,... You are watching: What is the least common multiple of 3 and 5 |

The multiples of 5 are: 5,10,15,20,25,30,35,40,45,50,... |

## What is a "Common Multiple" ?

Say we have detailed the first couple of multiples the **4** and also **5**: the **common multiples** space those the are found in both lists:

The multiples that 4 are: 4,8,12,16,20,24,28,32,36,40,44,... |

The multiples that 5 are: 5,10,15,20,25,30,35,40,45,50,... |

Notice that **20** and **40** appear in both lists? **So, the typical multiples that 4 and also 5 are: 20, 40,** (and **60**, **80**, etc ..., too)

## What is the "Least usual Multiple" ?

It is merely the **smallest** that the typical multiples.

In our previous example, the the smallest of the common multiples is **20** ...

... Therefore the **Least** common Multiple that 4 and 5 is **20**.

## recognize the Least common Multiple

List the multiples the the numbers till we gain our an initial match.

### Example: discover the least usual multiple of 4 and 10:

The multiples of 4 are: **4, 8, 12, 16, 20, ...****and the multiples of 10 are: 10, 20, ...**

Aha! there is a enhance at 20. That looks like this:

So the least common multiple of 4 and also 10 is **20**

### Example: find the least typical multiple that 6 and 15:

The multiples of 6 are: **6, 12, 18, 24, 30, ...****and the multiples that 15 are: 15, 30, ...**

There is a enhance at 30

So the least usual multiple the 6 and 15 is **30**

### Example: find the least common multiple that 4, 6, and 8

Multiples the 4 are: 4, 8, 12, 16, 20, **24**, 28, 32, 36, ...**Multiples the 6 are: 6, 12, 18, 24**, 30, 36, ...**Multiples that 8 are: 8, 16, 24**, 32, 40, ....

So **24** is the least common multiple (I can"t find a smaller one!)

Hint: We have the right to have smaller lists because that the larger numbers.

## Least usual Multiple Tool

There is an additional method: the Least common Multiple tool does that automatically. (Yes, we waited till the end to tell you!)
