Because they're designed that way. A tuning fork can be, well, "tuned" to have any desired frequency.
If these are for tuning Musical Instruments, they sound like very old Tuning Forks. The "middle C = 256 Hz" scale was in limited use at one time, but by modern standards (where the A above middle C is tuned to 440 Hz, or in some cases even higher) is a bit on the low side. Tuning your instrument to C=256Hz will make it sound "flat".
A tuning fork of 256 Hz will resonate with a 512 Hz frequency because the latter is a harmonic of the former. Specifically, 512 Hz is the second harmonic of 256 Hz, meaning it is a whole number multiple (2x) of the fundamental frequency. When the 512 Hz frequency is present, it causes the 256 Hz fork to vibrate in sympathy, resulting in resonance. This phenomenon occurs due to the principle of resonance, where an object vibrates at its natural frequency when exposed to a matching frequency.
The loudness of sound produced by a tuning fork depends on several factors, including the amplitude of the vibrations rather than just the frequency. However, in general, human perception of loudness is more sensitive to higher frequencies. Thus, while the 256 Hz tuning fork may be perceived as louder to the average human ear, the actual loudness will depend on the specific design and construction of the tuning forks.
The velocity of sound in air can be calculated using the formula ( v = 331.5 + 0.6T ), where ( T ) is the temperature in degrees Celsius. At 25 degrees Celsius, the velocity of sound would be ( v = 331.5 + 0.6 \times 25 = 346.0 ) meters per second. Therefore, the velocity of the sound emitted by the tuning fork with a frequency of 256 Hz at 25 degrees Celsius is approximately 346 m/s.
When two objects vibrate at frequencies of 256 Hz and 258 Hz, the difference in their frequencies creates a phenomenon known as beats. The beat frequency is calculated by subtracting the lower frequency from the higher frequency: 258 Hz - 256 Hz = 2 Hz. Therefore, two beats would be produced per second as a result of the interference between the two sound waves.
The vibrational speed of middle c (256 hz) in the well tempered and equal tempered tuning allows for the most aurally pleasing notes, so it is the key around which the pitches of all the other keys are determined.

The GCF is 128.
128
128 + 128 = 256 16 x 16 = 256
16,384 is my best guess. -256/2 = -128 -128 + -128 = -256 -128 * -128 = 16384.
256
128 x 2 = 256
The answer to that is 256.
256
The multiples of 128 between 1 and 362 are 128, 256, and 384.
