3355

3355 is a natural number that follows 3354 and precedes 3356. It is odd and composite. The prime factorization is 5 × 11 × 61, giving eight positive divisors: 1, 5, 11, 55, 61, 305, 671, and 3355.

In decimal form, the sum of the digits is 16, so 3355 is not divisible by 3 or 9. Since it ends in 5, it is divisible by 5. Other small divisors include 11, 61, 55, 305, and 671. In binary, 3355 is 110100011011, and in hexadecimal it is D1B. In Roman numerals it is written as MMMCCCLV.

In astronomy, minor planets are assigned sequential numbers once their orbits are well established. Therefore, 3355 would designate the 3355th cataloged minor planet, with the formal name usually including a provisional designation before the number. Beyond astronomy, 3355 can also appear as a model number, a catalog identifier, or a reference value in mathematical examples.

As a mathematical object, 3355 serves as an illustrative example of a product of three distinct primes and of divisor-counting properties. Its factorization into 5, 11, and 61 makes it a straightforward case for teaching basic arithmetic and number theory concepts.
