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