4487

4487 is a natural number that follows 4486 and precedes 4488. In mathematics, it is an odd composite number. Its prime factorization is 7 times 641, so its only positive divisors are 1, 7, 641, and 4487. This makes 4487 a semiprime, a product of two primes.

The sum of its proper divisors (1 + 7 + 641) is 649, which is less than 4487, so 4487 is a deficient number. The digit sum is 23, and in various modular arithmetic checks it is congruent to 2 modulo 3 and to 7 modulo 8.

In astronomy, the number 4487 is used as the designation for a minor planet in the catalog of discovered asteroids; such numbers are assigned sequentially as discoveries are confirmed, and the object may later receive a name.

There is no widely recognized cultural or mathematical significance attached to 4487 beyond these standard properties, but like other integers it features in studies of factorization, divisibility, and number representations.
