Detailed walkthrough
The factions you need to talk to are:


 * The Boomers at Nellis Air Force Base
 * The Brotherhood of Steel at Hidden Valley
 * The Great Khans at Red Rock Canyon
 * The Omertas at Gomorrah Casino
 * The White Glove Society at The Ultra-Luxe Casino

Each of these factions can be met in any order, and all have a quest associated with them. If you tell the Yes Man to ignore the faction you do not have to complete their quest to finish Side Bets, but many of the factions will aid you in the battle for Hoover Dam if you choose to complete their side-quest chain. Even if you've told Yes Man to ignore a faction you can go back once you've earned their assistance and change your opinion of them through dialogue.

Essentially this quest is just a guidepost quest that points you to the other factions, actually earning their aid or solving their problems requires you to complete a side-quest that usually gives you reputation (reputation with The Strip for the casinos, or with the Boomers, BoS or Khans respectively) and sometimes special benefits.

Brotherhood of Steel
Hidden Valley is a fenced in area that has an odd phenomena during the night when you enter it looks like a lighting storm is occurring above you (ignore this). A few underground bunkers all of them have a door at the the bottom of the steps in a mostly empty, collapsed room. You'll need to pick these (Some are very hard.), each room has some ammo in this collapsed room.(Be careful here, getting stuck is very easy while jumping around these collapsed rooms for ammo, but it's worth it. [Mini nukes 5mm ammo and missles.].) The last bunker you find as a door to pick but before you get a chance you will be interrupted by two brotherhood paladins. They will ask you to strip down to your underwear to enter and meet there leader if you want to side with them. Comply, if not you've got a heck of a fight on your hands For the Brotherhood of Steel, you have two solutions:
 * Destroy Hidden Valley. Hack the self-destruction terminal on second floor (Very hard), or pickpocket 3 keycards (from Elder McNamara, Head Paladin Hardin and Head Scribe Taggat) so you can generate password for self-destruction. When you activate the self-destruction protocol, the whole base will go hostile. Hacking the turret control console in Paladin Ramos' room, and set the turrets attack Brotherhood of Steel members might be helpful.
 * Convince the Brotherhood of Steel to support the NCR. Follow the NCR quest line until you reach For the Republic, Part 2. Colonel Moore will ask you to eradicate the Brotherhood, and you can negotiate with the Brotherhood Elder. Elder McNamara will, after some convincing, support the NCR to avoid conflict with them.  However, if you have helped Head Paladin Hardin to become Elder, he will not ally the Brotherhood with the NCR under any circumstances. You can report to Yes Man instead of Colonel Moore.

Boomers
To solve the Boomers' problems you must complete the quest Volare!, which will earn you their assistance in the Battle of Hoover Dam (by way of a pre-war heavy bomber) and the ability to come and go freely from Nellis.THUMP THUMP which is a souped up grenade launcher, and ample 5mm ammo and all types of grenades can be found in the "Ant Misbehavin'" side question at Nellis AFB. Also if you want to pick up the "re-breather" you can acquire it from Jack and Loyal after getting leader Pearl to side with you she asks for help raising the bomber out of lake mead and in order to successfully complete this you'll need to find some spare parts for Jack to build the "re-breather" or if you have a high enough repair skill you can tell him how to make it from things he already has on hand.

Great Khans
The Great Khans can either be convinced to help you (by completing the quest Oh my Papa) or to leave the Mojave for more fruitful areas. Or, they can be exterminated completely. It is also possible to get the Khans to suicide bomb Hoover Dam during the final battle through a speech check (75) with Papa Khan after you've gotten him to break the alliance with Caesar's Legion.

White Glove Society
By dealing with the White Glove Society's problems with cannibalism during the quest Beyond the Beef, you can tell Yes Man that you fixed their problem, solving their portion of the quest.

Omertas
At the Gomorrah you can pick up the quest How Little We Know. If you choose to aid Cachino in breaking up what the bosses have planned then you can inform Yes Man of this fact.

Once all the factions have either been ignored or their side-quests done, the player must simply talk to Yes Man again to complete the quest.

This quest is probably the longest in the game, simply for the fact it has five components, each of which is a quest chain with between 2 and 7 parts.
