least common multiple

Calling Sequence

[pp, fact] = lcm(p)



a polynomial row vector p = [p1, ..., pn] (type equal to 2) or an integer row vector (type equal to 1 or 8).


a polynomial vector or an integer vector.


a polynomial or an integer.


pp = lcm(p) computes the lcm pp of polynomial vector p.

[pp, fact] = lcm(p) computes in addition the vector fact such that:

p.*fact = pp*ones(p).

The least common multiple of an array p of real numbers can be obtained by converting it to a polynomial before calling lcm, through p = inv_coeff(p, 0).


// Polynomial case
s = %s;
p = [s s*(s+1)^2 s^2*(s+2)];
[pp,fact] = lcm(p);
p.*fact, pp

// Integer case
V = int32([2^2*3^5 2^3*3^2 2^2*3^4*5]);

// Double case
V = [2^2*3^5  2^3*3^2 2^2*3^4*5];
