# lcm

least common multiple

### Syntax

`[pp, fact] = lcm(p)`

### Arguments

p

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

fact

a polynomial vector or an integer vector.

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)`.

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)`.

If `p` is given as an integer double (type 1), then it is treated as an `int32`.

### Examples

```// 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]);
lcm(V)

// Double case
V = [2^2*3^5, 2^3*3^2,2^2*3^4*5];
lcm(V)```
