125 (ones hundred [and] twenty-five) is the natural number following 124 and preceding 126.
125 is the cube of 5. 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 factors are counted as often as they occur.
Like many other powers of 5, it is a Friedman number in base 10 since 125 = 51 + 2.
