Following is a partial FFT result. I want to extract the dominant
frequency out of it.

 Freq.    Real      Im.
 437     40.004   -123.185
 438     59.129   -182.045
 439    113.026   -347.923
 440   1244.858  -3831.345
 441   -138.493    426.170
 442    -65.685    202.089
 443    -43.090    132.547

In this case, I know the solution, it's a perfect f=440.1Hz re=0, im=-4096.
Is there an algorithm to find this value ?
There is no answer at this time.
