Question

multiplii și divizorii tuturor numerelor de la 1 la 50​

Answer 1

Multiplii unui număr 'n':

• reprezintă mulțimea numerelor de forma n•k, k ∈ ℕ.

Divizorii unui număr 'n':

• sunt numerele care divid numărul 'n', adică restul împărțirii cu 'n' este 0.

Numerele prime sunt acelea care au doar doi divizori, iar aceia sunt 1 și numărul însuși.
