If you need this info for Document Library, you can use

public static long getDefaultCompanyId(){
        long companyId = 0;
        try{ companyId = getDefaultCompany().getCompanyId(); }
        catch(Exception e){ System.out.println(e.getClass() + " " +e.getMessage()); }
       return companyId;
}

public static long getDefaultGroupId (){

    long companyId = getDefaultCompanyId();
    long globalGroupId = 0L;

    Group group = null;
    try {
        group = GroupLocalServiceUtil.getGroup(companyId, "Guest");
    } catch (PortalException | SystemException e) {
        e.printStackTrace();
        return globalGroupId;
    }
     globalGroupId = group.getGroupId();


    return globalGroupId;
}
