2. Divisor - Wikipedia

   en.wikipedia.org/wiki/Divisor

   For example, there are six divisors of 4; they are 1, 2, 4, −1, −2, and −4, but only the positive ones (1, 2, and 4) would usually be mentioned. 1 and −1 divide (are divisors of) every integer. Every integer (and its negation) is a divisor of itself. Integers divisible by 2 are called even, and integers not divisible by 2 are called odd.

3. Amicable numbers - Wikipedia

   en.wikipedia.org/wiki/Amicable_numbers

   In mathematics, the amicable numbers are two different natural numbers related in such a way that the sum of the proper divisors of each is equal to the other number. That is, s(a)=b and s(b)=a, where s(n)=σ(n)-n is equal to the sum of positive divisors of n except n itself (see also divisor function). The smallest pair of amicable numbers is ...

4. Divisor function - Wikipedia

   en.wikipedia.org/wiki/Divisor_function

   Divisor function σ 0 (n) up to n = 250 Sigma function σ 1 (n) up to n = 250 Sum of the squares of divisors, σ 2 (n), up to n = 250 Sum of cubes of divisors, σ 3 (n) up to n = 250 In mathematics , and specifically in number theory , a divisor function is an arithmetic function related to the divisors of an integer .

5. Remainder - Wikipedia

   en.wikipedia.org/wiki/Remainder

   43 = (−9) × (−5) + (−2) and −2 is the least absolute remainder. In the division of 42 by 5, we have: 42 = 8 × 5 + 2, and since 2 < 5/2, 2 is both the least positive remainder and the least absolute remainder. In these examples, the (negative) least absolute remainder is obtained from the least positive remainder by subtracting 5 ...

6. Divisor (algebraic geometry) - Wikipedia

   en.wikipedia.org/wiki/Divisor_(algebraic_geometry)

   Let X be the quadric cone of dimension 2, defined by the equation xy = z 2 in affine 3-space over a field. Then the line D in X defined by x = z = 0 is not principal on X near the origin. Note that D can be defined as a set by one equation on X , namely x = 0; but the function x on X vanishes to order 2 along D , and so we only find that 2 D is ...

8. Division (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Division_(mathematics)

   This is denoted as 20 / 5 = 4, or ⁠ 20 / 5 ⁠ = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is the quotient. Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend; for example, 10 / 3 leaves a
