**LCM( 9, 6 ) = 18**

**Step 1: **Write down factorisation of each number:

9 = 3 · 3

6 = 2 · 3

**Step 2 : ** Match primes vertically:

9 | = | 3 | · | 3 | ||

6 | = | 2 | · | 3 |

**Step 3** : Bring down numbers in each column and multiply to get LCM:

9 | = | 3 | · | 3 | ||||

6 | = | 2 | · | 3 | ||||

LCM | = | 2 | · | 3 | · | 3 | = | 18 |

**This solution can be visualized using a Venn diagram.**

The LCM is equal to the product of all the numbers on the diagram.
