7380

7380 is a natural number in the decimal numeral system, immediately following 7379 and preceding 7381. It has applications in mathematics as an example number in lessons about divisibility, factorization, and number theory.

Mathematical properties: 7380 is even, divisible by 2, 3, 5, and 9. The sum of its digits is 18, which means it is divisible by 9 and 3; hence 7380 is a Harshad (Niven) number in base 10. Its prime factorization is 2^2 × 3^2 × 5 × 41, giving it 36 positive divisors.

Divisibility and structure: because it ends in 0, 7380 is divisible by 10 and by 20; in fact 7380 = 60 × 123, showing it is a multiple of 60. It is not a prime, nor a perfect square or cube, and it is a four-digit integer in decimal notation.

Abundance and growth: the sum of proper divisors of 7380 is 15552, larger than 7380, so 7380 is an abundant number. It is also composite and not part of the sequence of highly composite numbers, since a smaller number (such as 1260) already has the same divisor count of 36.

In other contexts: as a four-digit decimal, 7380 may appear in counting, coding, or labeling schemes. Like many integers, it has no singular widely recognized meaning beyond its mathematical properties, and references to 7380 are typically contextual.
