The factors are:
The length of the pendulum.
The construction of the pendulum. Its distribution of weight determines its center of gravity and moment of inertia. Its actual mass does not matter.
The height above sea level. This will very slightly change the gravitational acceleration g. Similarly any large masses close to the pendulum can also very slightly change its acceleration.
The angle of the swing. For small angles the period is constant. However, if the swing gets large this is not true.
The other answers so far given are incomplete and do not take into account important factors in addition to length gravity and/or c of g.

Only two factors to worry about:
1. Length of pendulum,L.
2. Acceleration of gravity, g.
Period = 2Ï*sqrt[ L / g ]

Absolutely the length of the pendulum, gravity is a constant of 1G, the mass of the pendulum weight is the other factor.

center of gravity and distance from the center of the pendulum axis, and air resistance. next is mechanical machining methods.
