Number 4 — Four

The number 4 is written with one or two Western digits from the Hindu–Arabic numeral system. It is even and composite. Its positive divisors are 1, 2, 4. Additional properties include being a perfect square. These mathematical properties are verifiable; religious, esoteric, and numerological readings depend on a particular tradition and are not properties of the number itself. Numerological reading: the number is associated with order, foundation, and the four elements. In a talismanic or meditative composition it may express an intention to focus on these qualities; meanings vary by school and context.
