Granville smooth numbers
WebIn number theory, an n-smooth (or n-friable) number is an integer whose prime factors are all less than or equal to n. For example, a 7-smooth number is a number whose every prime factor is at most 7, so 49 = 7 2 and 15750 = 2 × 3 2 × 5 3 × 7 are both 7-smooth, while 11 and 702 = 2 × 3 3 × 13 are not 7-smooth. The term seems to have been coined … WebMore interesting perhaps are those abundant numbers that turn out to be. S. -perfect since the excluded divisors turn out to add up to the number’s abundance. Some such …
