# LCM Command

From GeoGebra Manual

UK English: LCM = lowest common multiple

- LCM( <Number>, <Number> )
- Calculates the least common multiple of two numbers.
**Example:**`LCM(12, 15)`

yields*60*.

- LCM( <List of Numbers> )
- Calculates the least common multiple of the elements in the list.
**Example:**`LCM({12, 30, 18})`

yields*180*.

**Hint:**In the CAS View you can also use the following syntax:

- LCM( <Polynomial>, <Polynomial> )
- Calculates the least common multiple of the two polynomials.
**Example:**`LCM(x^2 + 4 x + 4, x^2 - x - 6)`

yields x^3 + x^2 - 8 x - 12.

- LCM( <List of Polynomials> )
- Calculates the least common multiple of the polynomials in the list.
**Example:**`LCM({x^2 + 4 x + 4, x^2 - x - 6, x^3 - 4 x^2 - 3 x + 18})`

yields x^4 - 2 x^3 - 11 x^2 + 12 x + 36.
