8780

8780 is the natural number that follows 8779 and precedes 8781. It is an even and composite integer. Its prime factorization is 2^2 × 5 × 439, where 439 is a prime number. This factorization yields 12 positive divisors: 1, 2, 4, 5, 10, 20, 439, 878, 1756, 2195, 4390, and 8780. The sum of all divisors is 18480, so 8780 is an abundant number since the sum of its proper divisors (18480 − 8780 = 9700) exceeds the number itself.

In several base systems, 8780 is represented as 0x224C in hexadecimal, as 21114 in octal, and as 10001001001100 in binary. In base 5 it equals 240110_5.

Geometrically or in common sequences, 8780 does not hold notable special status: it is not prime, not a Fibonacci number, and not a perfect square. In practical terms, 8780 minutes equal 146 hours and 20 minutes, or six days, two hours, and twenty minutes, which can be relevant for time conversions.

As a year, 8780 could refer to a date in distant past or future contexts, but it is not associated with widely recognized historical events. Overall, 8780 is primarily of interest in number-theory contexts due to its factorization and divisor structure.
