    ## S3 method for class 'polylist'
    LCM(...)
    ## S3 method for class 'polynomial'
    LCM(...)

### Arguments

`...` | a list of objects of class `polynomial` or `polylist`.

### Examples

    pl <- polylist(poly.from.roots(-1),
                   poly.from.roots(c(-1, -1)),
                   poly.from.roots(1))
    GCD(pl)
    GCD(pl[-3])
    LCM(pl)
