The 6th string in standard tuning, E2, is 82.41 Hz at A4 = 440 Hz.
The 1st string, E4, is 329.63 Hz, two octaves above the low E.
In equal temperament, the modern tuning system, each semitone up multiplies the frequency by the twelfth root of two. That number has endless decimals, so at A4 = 440 Hz only A notes come out as round numbers.
