First, take any number (for this example it will be 376) and note the last digit in the number, discarding the other digits. Then take that digit (6) while ignoring the rest of the number and determine if it is divisible by 2. If it is divisible by 2,...

Xem thêmTo test for divisibility by D, where D ends in 1, 3, 7, or 9, the following method can be used. Find any multiple of D ending in 9. (If D ends respectively in 1, 3, 7, or 9, then multiply by 9, 3, 7, or 1.) Then add 1 and divide by 10, denoting the result as m. Then a number N = 10t + q

https://en.wikipedia.org/wiki/Divisibility_(ring_theory)In mathematics, the notion of a divisor originally arose within the context of arithmetic of whole numbers. With the development of abstract rings, of which the integers are the archetype, the original notion of divisor found a natural extension.
Divisibility is a useful concept for the analysis of the structure of commutative rings because of its relationship with the ideal structure of such rings.Wikipedia · Nội dung trong CC-BY-SA giấy phépDivisibility rules - Simple English Wikipedia, the free ...

When the ones digit of the number is either 0 or 5. Eg:- 55, 125, 1000, 760 Divisibility Rule of 6. A number is divisible by 6 if it is divisible by 2 and 3 also.

https://fr.wikipedia.org/wiki/Divisibilité- Dans l'ensemble des entiers naturels
La notion de divisibilité est originaire de la notion de distribution en parts égales et est associée à la notion de division euclidienne : pour tous entiers naturels non nuls, a est divisible par b si et seulement si la division euclidienne de a par best exacte (i.e. a pour reste 0). La définition précé… - Dans l'ensemble des entiers relatifs
La notion de divisibilité s'étend à l'ensemble des entiers relatifs en utilisant la même définition. On peut remarquer que a divise b si et seulement si |a| divise |b|. La relation « divise » dans l'ensemble des entiers relatifs possède presque les mêmes propriétés que dans l'ensemble des entiers natu…

https://es.wikipedia.org/wiki/Divisibilidad- El número entero a {\displaystyle a} es divisible entre el número entero b ≠ 0 {\displaystyle b\neq 0} (o lo que es lo mismo, b divide a a) si hay un número q {\displaystyle q} entero, tal que a = b ⋅ q {\displaystyle a=b\cdot q} . Este hecho se denomina divisibilidad del número entero a {\displaystyle a} por el número entero b {\displaystyle b} y se denota por b | a {\displaystyle b|a} …

Première méthode : Un nombre est divisible par 7 si et seulement si la somme de son nombre de dizaines et de cinq fois son chiffre des unités l'est.

Une méthode, basée seulement sur le fait que 103 est congru à –1 modulo 7, est de séparer ce nombre par tranches de 3 chiffres en partant des unités et d'insérer alternativement des – et des + entre les tranches. On effectue l'opération ainsi écrite et ce résultat est divisible par 7 si et seul…

Criteri di divisibilità - Wikipedia
https://it.wikipedia.org/wiki/Criteri_di_divisibilitàIn aritmetica, i criteri di divisibilità sono degli algoritmi che permettono di verificare la divisibilità di un numero intero per un fattore senza eseguire la divisione esplicita.. Consistono in una serie di operazioni sulle cifre che compongono il numero. Tali operazioni dovrebbero essere sufficientemente semplici da potersi fare a mente, o comunque essere più rapide rispetto alla …
