Because gear ratio can increase or decrease output torque by a factor of the gear ratio, not accounting for friction losses.

From Wikipedia:
A gear train can be analyzed using the principle of virtual work to show that its torque ratio, which is the ratio of its output torque to its input torque, is equal to the gear ratio, or speed ratio, of the gear train.

This means that the input torque TA applied to the input gear GA and the output torque TB" on the output gear GB are related by the ratio

where R is the gear ratio of the gear train.
