Will You Lose Your Apps When You reset your iPhone?

Will u lose all your apps when you tap on "Erase Content and Settings" on your iPhone?
Because i recently paid for a few apps.

Er - erase CONTENT duhh, course you will.

Yes all your memory on your IOS device will be wiped out completely back to the factory settings (like if you bought the device) however the apps you previously downloaded on with your apple ID you can download them on any device if signed in to it i would recommend saving your memory on your computer with I cloud (depends what your doing if you want to save your memory)

YES, that is what a "factory reset" means, like it just came from the factory.
