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.
Note: See also GCD Command.
