powering 3 different LEDs with 1 CC driver

I have a few questions about using an LED driver (15V 700mA CC driver) to power  3 LEDs with different Vf and forward current requirements: 

Vf 3.2 - 3.6V   700mA   

Vf 3.5 - 4.5V  750mA

Vf 3.4 - 4.0V  750mA

1. How does a CC led driver 'determine'  the voltage that is needed in order to reach the 700mA? 

2. What voltage will the driver provide at 700mA,  is this 3x 3.5V = 10.5V? (because if 10.4V is provided, the Vf 3.5 of one of the LEDs is not met, so a current can't run:  does it work this way?)

3. Will each LED draw 7.35W (10.5V x 700mA) /3 = 2.45W? 

Thanks!
