You have a 240-ohm, a 670-ohm, and a 1.30-kiloOhm resistor.
I know the minimum is using 1/R1 + 1/R2 + ..., but I don't know how to find the max. Help? Thanks.

The maximum Resistance obtained by your resistors depends upon how they are wired in your circuits and the type of current that is applied.
Applying Ohm's law (for a DIRECT CURRENT source) E(voltage)=I(current)*Resistance
Applying Kirchoff's law (for an ALTERNATING CURRENT source)
Xl=2pi*frequency*Inductance (L)
This ^ formula calculates the Inductive Reactance in an AC circuit
Xc= 1/ 2pi*frequency*capacity (C) calculates the Capacitive reactance in an AC circuit.
GOOD LUCK!

Just connect them in series. It's
Rt = R1 + R2 + R3 + ........
