Current through one LED in series with 68 kΩ:

68 kΩ is a standard value in the E6, E12, E24 series, so it comes in almost every resistor kit.

Same first two colors, different multiplier:

What are the colors of a 68 kΩ resistor?

On a 4-band resistor: blue, grey, orange, gold. On a 5-band resistor: blue, grey, black, red, brown.

What is the SMD code for 68 kΩ?

683 on 3-digit resistors and 6802 on 4-digit (1%) resistors.

How much current flows through a 68 kΩ resistor at 5 V?

73.5 µA, dissipating 368 µW. A 1/8 W resistor is enough.

Which resistors get mixed up with 68 kΩ?

blue, grey, red, gold is 6.8 kΩ and blue, grey, yellow, gold is 680 kΩ: only the third band changes, so check it carefully.
