4773

4773 is a natural number that follows 4772 and precedes 4774. In mathematics, it is an odd composite number with prime factorization 3 × 37 × 43. Because it is the product of three distinct primes, 4773 is classified as a sphenic number.

Its positive divisors are 1, 3, 37, 43, 111 (3 × 37), 129 (3 × 43), 1591 (37 × 43), and 4773 itself. The sum of all divisors is 6688, which means the sum of its proper divisors (excluding 4773) is 1915. The number is divisible by 3, 37, and 43, and by the combinations 111, 129, and 1591 as well.

In base 2, 4773 is represented as 1001010100101. It is not a Harshad number in base 10, since the sum of its digits is 21 and 21 does not divide 4773.

Beyond these arithmetic properties, 4773 does not have widely noted special significance in common mathematical tables or widely known cultural references. Its characterization as a sphenic number and its explicit factorization are its most notable features in standard number-theory contexts.
