120013

120013 is a natural number that follows 120012 and precedes 120014. As a six-digit decimal integer, it is odd and not divisible by 2, 3, or 5: the sum of its digits is 7, so it is not a multiple of 3, and the last digit is 3. By divisibility tests, it is not divisible by 7 or 11 either: 120,013 divided by 7 leaves a remainder of 5, and the alternating sum of digits (1-2+0-0+1-3) equals -3, which is not a multiple of 11. It is congruent to 7 modulo 9, and its digital root is 7.

In mathematics, 120013 is one member of the natural numbers; beyond its basic arithmetic properties, it does not carry special significance by itself. In other domains, sequences of numbers such as 120013 are often used as designations or catalog identifiers for objects, records, or entries. For example, such numbers can appear in astronomy as minor planet or asteroid numbers, in corporate or library catalogs as identifiers, or as serial numbers in products or datasets. On its own, the designation 120013 carries no inherent meaning without a referencing system.

If a particular field assigns a specific object to the number, information about that object would be found within the corresponding catalog entry rather than in the number alone.
