Final answer:
Pythagoras lived the longest among the three Greek philosophers, with an estimated lifespan of around 85 years, followed by Plato who lived about 80 years, and Aristotle with 62 years.
Step-by-step explanation:
To determine which of the three Greek philosophers lived the longest, we simply need to calculate the lifespan of each based on the years provided. Aristotle was born in 384 BCE and died in 322 BCE, giving him a lifespan of 62 years. Pythagoras was born around 580 BCE and died around 495 BCE, which suggests he lived approximately 85 years. Lastly, Plato was born in 428 BCE and died in 348 BCE, making his lifespan approximately 80 years.
Based on these calculations, it is Pythagoras who lived the longest, with an estimated lifespan of around 85 years. This is longer than the lifespans of both Plato, who lived about 80 years, and Aristotle, who lived 62 years. Pythagoras's longevity for the time was quite remarkable, especially considering the average life expectancy in ancient Greece was much lower than what we experience today.
