 ## How to find the Least Common Multiple of 40 and 44?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 40 and 44.

Follow the steps below, and let's calculate the LCM of 40 and 44.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 40 and 44:

##### Prime factors of 40

The prime factors of 40 are 2, 2, 2 and 5. Prime factorization of 40 in exponential form is:

40 = 23x51

##### Prime factors of 44

The prime factors of 44 are 2, 2 and 11. Prime factorization of 44 in exponential form is:

44 = 22x111

23, 51, 111

23x51x111=440

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 40 and 44.

The Least Common Multiple of 40 and 44 is 440.

### Method 2 - List of Multiples

Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.

#### Multiples of 40:

40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560

#### Multiples of 44:

44, 88, 132, 176, 220, 264, 308, 352, 396, 440, 484, 528, 572

#### Therefore,

LCM(40, 44) = 440
