The tables below list all of the divisors of the numbers 1 to 1000. A divisor of an integer n is an integer m , for which n / m is again an integer (which is necessarily also a divisor of n ). For example, 3 is a divisor of 21, since 21/7 = 3 (and therefore 7 is also a divisor of 21).
In number theory, the aliquot sum s(n) of a positive integer n is the sum of all proper divisors of n, that is, all divisors of n other than n itself. That is, = |,. It can be used to characterize the prime numbers, perfect numbers, sociable numbers, deficient numbers, abundant numbers, and untouchable numbers, and to define the aliquot sequence of a number.
Demonstration of the practicality of the number 12. In number theory, a practical number or panarithmic number [1] is a positive integer such that all smaller positive integers can be represented as sums of distinct divisors of .
Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.
Let (,) denote the multiplicative inverse of modulo , namely the least positive integer such that =, and for each unitary divisor of let = and () = (,). Then the function ζ {\displaystyle \zeta } is a bijection from the set of unitary divisors of N − 1 {\displaystyle N-1} onto the set K ( N ) {\displaystyle K(N)} .
While it might seem like a celery stalk refers to a single piece of celery, the term actually refers to the entire bunch, including all the individual ribs, as well as the leafy tops.
