<br/>(Wikipedia, L'Encylopédie Libre, <a href="https://fr.wikipedia.org/wiki/Entier_friable">https://fr.wikipedia.org/wiki/Entier_friable</a>)"""@fr, """In number theory, an <b><i>n</i>-smooth</b> (or <b><i>n</i>-friable</b>) <b>number</b> is an integer whose prime factors are all less than or equal to <i>n</i>. For example, a 7-smooth number is a number whose every prime factor is at most 7, so 49 = 7<sup>2</sup> and 15750 = 2 × 3<sup>2</sup> × 5<sup>3</sup> × 7 are both 7-smooth, while 11 and 702 = 2 × 3<sup>3</sup> × 13 are not 7-smooth. The term seems to have been coined by Leonard Adleman. Smooth numbers are especially important in cryptography, which relies on factorization of integers. The 2-smooth numbers are just the powers of 2, while 5-smooth numbers are known as regular numbers.
