Synopsis#include <flint/fmpq_poly.h>
void _fmpq_poly_lcm(fmpz * L, fmpz_t denL, const fmpz * A, slong lenA, const fmpz * B, slong lenB)source

Computes the monic least common multiple LL of AA and BB.

Assumes that LL has space for len⁡(A)+len⁡(B)−1\operatorname{len}(A) + \operatorname{len}(B) - 1 coefficients, where len⁡(A)≥len⁡(B)>0\operatorname{len}(A) \geq \operatorname{len}(B) > 0.

Aliasing between the output and input arguments is not supported.

Does not support zero-padding.
