It all depends on how big a star is. The more massive a star is the shorter the life span.

A blue/white supergiant could last for 10 million years whereas a small red dwarf could last for trillions of years.

That depend on how much mass comprises the star. Heavy stars last only a few million years, small red dwarf stars can last for trillions of years.
