lcm

Arguments

p

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

fact

a polynomial vector or an integer vector (type equal to 8).

pp

a polynomial or an integer.

Description

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).

Examples

//polynomial case
s=poly(0,'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]);
lcm(V)
