NWD

NWD is an acronym with multiple meanings across different domains. In Polish mathematics, NWD stands for Największy wspólny dzielnik, the greatest common divisor of integers. It is the largest positive integer that divides each of the given numbers without a remainder. The gcd is symmetric and can be computed efficiently by the Euclidean algorithm. For a set of numbers, gcd(a, b, c, ...) is the gcd of the gcds of pairs, and it plays a central role in simplifying fractions and solving Diophantine problems. For example, NWD(28, 42) equals 14, and any common divisor of 28 and 42 must also divide 14.

In business and corporate contexts, NWD is commonly used as the abbreviation for New World Development Company Limited, a Hong Kong-based property and infrastructure conglomerate. The company engages in property development and investment, hospitality and hotel management, and related infrastructure projects. It is a publicly traded entity on the Hong Kong Stock Exchange, and NWD appears in financial reporting and news coverage as a shorthand reference to the group.

Outside of mathematics and this corporate usage, NWD can have other meanings in various languages and sectors, reflecting different organizations, initiatives, or standards. Because the acronym is context-dependent, the intended meaning of NWD should be inferred from the surrounding text.
