38 is a natural number that comes between 37 and 39. It is written in standard Hindu-Arabic numerals and has two digits: 3 (tens place) and 8 (ones place).
Like other numbers, 38 can be used in two ways: as a count (how many things) and as a label (for example, a road number, a jersey number, or a team identifier). In mathematics, its properties are defined by its divisors and how it behaves in basic operations.
Mathematical properties
38 is an even number because 2 divides it evenly. Its divisors are 1, 2, 19, and 38. Therefore it is not prime; it is a composite number formed by the product of two primes: 2 × 19.
The sum of its proper divisors (those less than the number itself: 1 + 2 + 19) equals 22, which is less than 38. For this reason, 38 is classified as a deficient number, one whose proper divisors sum to less than the number itself.
Representation in different systems
In binary notation, 38 is written as 100110. In hexadecimal, it is 26. In Roman numerals it is expressed as XXXVIII.
Common use
The name of this number in Somali is 'sideed iyo soddon' (thirty-eight). It is commonly used in standard measurements such as age, height, and counting objects. It is also an identifier assigned to roads, buildings, and sports teams, in which context it carries no mathematical significance.
