Name
lcm — least common multiple
Calling Sequence
[pp,fact]=lcm(p)
Parameters
- 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)
