Basic rule to build present participle is to take verb from first plural person of indicative present. Then, replace inflexon ONS by ANT.
eg: fatiguer ==> nous fatiguons ==> fatiguantBut we need an exception. There is one with verb savoir: nous savons ==> sachant
For present gerundive, just add "en" in front of present participle and that's it.
