Division avec des nombres entiers

Exercice 1 : Somme des nombres multiples de deux nombres

Écrire un programme qui calcule et affiche la somme de tous les multiples de 2 ou 5 inférieurs ou égaux à 100.

Cet exercice est le premier abordé en entretien d'embauche pour les postes de développeurs chez Kwyk.

Exercice 2 : Ce nombre est-il premier ? Nombres entre 100 et 400

\( 193 \) est-il premier ?

Exercice 3 : Liste des facteurs premiers, nombres inférieurs à 100

Écrire \( 28 \) comme un produit de nombres premiers.
Les ranger ensuite dans une liste, dans l'ordre croissant, séparés par des points-virgules.
Par exemple pour \( 6 \) on écrira \( 2;3 \)

Exercice 4 : Somme des nombres multiples de deux nombres

Écrire un programme qui calcule et affiche la somme de tous les multiples de 5 ou 11 inférieurs ou égaux à 100.

Cet exercice est le premier abordé en entretien d'embauche pour les postes de développeurs chez Kwyk.

Exercice 5 : Ce nombre est-il premier ? Nombres entre 100 et 400

\( 347 \) est-il premier ?
