We demonstrate the ability of lattices of coupled chaotic maps to perform simple computations. This dynamical system is shown to emulate logic gates, encode numbers, and perform specific arithmetic operations on those numbers such as addition and multiplication. We also demonstrate the ability of this dynamical system to perform the more specialized operation of determining the least common multiplier of a sequence of integers.
