Method 1: By Listing Multiples

List out all multiples of each denominator, and find the first common one.

Multiples of 3 : 3, 6, ...

Multiples of 2 : 2, 4, 6, ...

Therefore, the LCD is

6

6.

Method 2: By Prime Factors

Since

3,2 are prime numbers themselves, we simply multiply them to get the LCD.

Therefore, the LCD is
