Here total inductance is l = 1/l1+(1/(l2+l3)). l = 1/450mh+1/(100mh+370mh). l = (10^6/450+10^6/470) = (2.22222+2.12766)10^6. l = 4.34988k. Nearest value is 4.4 kohms.

If the Inductors were all in parallel your calculation makes sense. Just calculate the Inductive reactance for the 450mH inductor the value is 2*PI*7000*(450X 10^3) = 19792 OHMs so the total reactance is higher than this value.

XL = 2 * Pi * f * L. Given: L2 = 100 mH. XL = 2 * 3.14 * 7 * 10^3 * 100 * 10^3. XL = 4396 Ohm. Nearly XL = 4.4 K Ohm.
