The current through each LED should still be same, so current through single resistor is 4x current through each resistor in the pack. Voltage drop should be same -> R_single should be R/4 (a quarter of the value of the resistors in the pack)

Unless I missed something obvious...

This setup is more sensitive to differences in V_forward among the 4 LEDs though.
