lcm

least common multiple

Calling Sequence

[pp,fact]=lcm(p)

Arguments

:p : :fact polynomial vector or integer vector (type equal to 8) : :pp polynomial or 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)
