130 (one hundred [and] thirty) is the natural number following 129 and preceding 131.

130 is a sphenic number. It is a noncototient since there is no answer to the equation x - φ(x) = 130.

130 is the only integer that is the sum of the squares of its first four divisors, including 1: 1² + 2² + 5² + 10² = 130.

130 is the largest number that cannot be written as the sum of four hexagonal numbers.^[1]

130 equals both 2⁷ + 2 and 5³ + 5 and is therefore a doubly strictly adsurd number.^[2]

The Book of Genesis states Adam had Seth at the age of 130. The Second Book of Chronicles says that Jehoiada died at the age of 130.^[3]

One hundred [and] thirty is also:

The year AD 130 or 130 BC
The 130 nanometer process is a semiconductor process technology by semiconductor companies
A 130-30 fund or a ratio up to 150/50 is a type of collective investment vehicle
