To find RMS we multiply peak amplitude by ________.

RMS value is the effective value that produces the same heating effect as the AC signal. For a sinusoidal waveform, the RMS equals the peak amplitude divided by the square root of 2. So you multiply the peak amplitude by 1/√2, which is about 0.707. The other numbers don’t match this relationship: 1.414 is √2 and would scale the peak up, not down; 0.5 and 0.353 are not the correct ratio for a sine wave.
