125 is the natural number
following 124
and preceding 126
.
It can be expressed as a sum of two squares in two different ways, 125 = 10² + 5² = 11² + 2².
125 and 126 form a Ruth-Aaron pair
under the second definition in which repeated prime factor
s are counted as often as they occur.
Like so many other powers of 5, it is a Friedman number
in base 10 since 125 = 51 + 2.
