471

471 is a natural number that lies between 470 and 472. It is an odd composite number with a prime factorization of 3 × 157, so its positive divisors are 1, 3, 157, and 471. In Roman numerals it is written as CDLXXI. In binary it equals 111010111₂, and in hexadecimal it is 0x1D7. The sum of its digits in base-10 is 4 + 7 + 1 = 12.

In mathematical contexts, 471 is notable for being the product of a small prime and a larger prime, making it semiprime. It is also the sum of three consecutive odd numbers: 149 + 151 + 171? (Note: this sum is not accurate; the correct property is that 471 can be expressed as 3 × 157 rather than as a simple consecutive-odd sum. The important point is its factorization.)

Historically and culturally, 471 can refer to the year 471 CE in the Common Era, placing it in the late classical/early medieval period of Europe and the surrounding regions. It is also the designation of a minor planet, 471 Papagena, which is a main-belt asteroid. The number 471 appears in various cataloging and numbering systems, where it serves as an identifying label rather than carrying inherent meaning beyond its numeric properties.

Overall, 471 is best described as a composite integer with straightforward representations in multiple bases, a simple factorization, and occasional usage as a year designation or asteroid number in broader reference works.
