11.2.7 LCM of two polynomials

The lcm command computes the LCM (Least Common Multiple) of polynomials. (See 7.1.3 for LCM of integers).

lcm takes polys, a sequence or list of polynomials.
lcm(polys) returns the least common multiple of the polynomials in polys.

Examples

lcm(x^2+2*x+1,x^2-1)

⎛
⎝

x+1

⎞
⎠

⎛
⎝

x²−1

⎞
⎠

lcm(x,x^2+2*x+1,x^2-1)

or:

lcm([x,x^2+2*x+1,x^2-1])

⎛
⎝

x²+x

⎞
⎠

⎛
⎝

x²−1

⎞
⎠
