WebFeb 27, 2015 · 5 It depends on the structure and/or your definition of proper divisor. If you say that a divisor d of b is proper if d ≠ b, then the proper divisors of 1 are exactly the invertible elements/units of the ambient structure except 1. That is none for N, − 1 for Z, − 1, i, i for Z [ i] and so on. WebThis tool calculates all divisors of the given number. An integer x is called a divisor (or a factor) of the number n if dividing n by x leaves no reminder. For example, for the number 6, the divisors are 1, 2, 3, 6, and for the number 7 only: 1, 7 (because it is a prime number ).

WebFor a number to have 8 divisors it should be either written in one of the 3 forms. p1 * p2 * p3 p1^3 * p2 p^7 because, from the formula 8 = 2 * 2 * 2 or 4 * 2 or 8 * 1. So If we know how many prime numbers are below n, we can find out the combinations that can have 8 divisors. p1*p2*p3: The maximum `p` can be `N / 2 * 3`.

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). If m is a divisor of n then so is −m. The tables below only list positive divisors. phoenix watchdog
