SUMMARY
The combined frequency of the sine waves represented by the equation y(t) = sin(2π10t) + sin(2π50t) + sin(2π100t) is determined by the lowest frequency component, which is 10 Hz. While the individual frequencies of 10 Hz, 50 Hz, and 100 Hz exist, the overall waveform is periodic with a fundamental period of 0.1 seconds, dictated by the 10 Hz sine wave. The concept of the least common multiple (LCM) does not apply in this context, as the resulting waveform is not a simple sinusoidal wave but a complex periodic waveform.
