11×43

11×43 denotes the product of the integers 11 and 43. The result is 473.

Both 11 and 43 are prime numbers, so 473 is a semiprime with exactly four positive divisors: 1, 11, 43, and 473.

Representations of 473 include binary 111011001, hexadecimal 1D9, and Roman numerals CDLXXIII. In decimal notation it is simply 473.

Calculation can be shown by distributive property: 11×43 = 11×40 + 11×3 = 440 + 33 = 473. It also illustrates a common shortcut for multiplying by 11: for a two-digit number such as 43, the product 11×43 can be read as 4, then the sum 4+3 = 7, and then 3, yielding 473.

In broader context, 11×43 serves as a straightforward example in elementary and intermediate number theory. It demonstrates the multiplication of primes, the concept of semiprimes, and how products can be represented in multiple numeral systems. The factorization 473 = 11×43 shows how composite numbers arise from prime factors, a foundational idea in arithmetic and algebra.
