1738

1738 is the natural number that follows 1737 and precedes 1739. It is an even, composite number.

Its prime factorization is 2 × 11 × 79, which can also be written as 22 × 79. The divisors of 1738 include 1, 2, 11, 22, 79, 158, 869, and 1738 (the last being the number itself). The sum of its proper divisors (excluding 1738) is 1142, which is less than 1738, so 1738 is a deficient number.

In various numeral systems, 1738 is represented as follows: in binary it is 11011001010, in octal it is 3312, and in hexadecimal it is 0x6CA. In Roman numerals, 1738 is written as MDCCXXXVIII.

From a mathematical standpoint, 1738 is not a prime, nor a square or a cube, and it does not belong to the Fibonacci sequence or to many common figurate number families. Its factorization and base representations are typical features of a mid-range composite integer.

As a plain integer, 1738 is primarily of interest in arithmetic and number theory contexts, where its factorization and representations illustrate how a single number can appear differently across numeral systems and how divisor sums relate to its classification as deficient.
