The lifetime of a main sequence star is inversely proportional to its mass.

Mass is the primary determinant of a star's position on the Main Sequence and its overall lifespan. More massive stars have higher core temperatures and pressures, leading to significantly faster rates of hydrogen fusion. While they possess more fuel, they consume it at such a prodigious rate that their main sequence lifetimes are much shorter than those of less massive stars. For example, a star ten times the mass of the Sun might live for only tens of millions of years, whereas a star one-tenth the Sun's mass could last for trillions of years.
