3470

3470 is a natural number that follows 3469 and precedes 3471. In mathematics it is an even, composite number with prime factorization 2 × 5 × 347, making it square-free. Its positive divisors are 1, 2, 5, 10, 347, 694, 1735, and 3470.

The sum of its decimal digits is 14, giving a digital root of 5. It is divisible by 2 and 5, and hence by 10, but not by 3. In modular terms, 3470 is congruent to 2 modulo 4 and to 6 modulo 8. The Euler totient function evaluates to φ(3470) = 1384, since 3470 = 2 × 5 × 347 with pairwise coprime factors, and φ(3470) = φ(2)φ(5)φ(347) = 1 × 4 × 346 = 1384.

In different numeral systems, 3470 can be represented as 110110001110 in binary and as D8E in hexadecimal. In Roman numerals it is written as MMMCDLXX.

3470 can also serve as a numeric identifier in various cataloging systems, product codes, or numbering schemes. As a concept, it remains primarily notable for its factorization, divisor structure, and standard base representations rather than for any singular mathematical exceptional property.
