LCM Command

UK English: LCM = lowest common multiple

LCM( <Number>, <Number> ): Calculates the least common multiple of two numbers.

LCM(12, 15) yields 60.

LCM( <List of Numbers> ): Calculates the least common multiple of the elements in the list.

LCM({12, 30, 18}) yields 180.

CAS Syntax

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

LCM( <Polynomial>, <Polynomial> ): Calculates the least common multiple of the two polynomials.

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.

LCM({x^2 + 4 x + 4, x^2 - x - 6, x^3 - 4 x^2 - 3 x + 18}) yields \(x^4 - 2 x^3 - 11 x^2 + 12 x + 36\).
