Cartus crezi ca toata lumea stie raspunsul la intrebarea aceasta? Eu nu cred. Cei care nu au treaba cu matematica nu cred ca stiu, sunt multi care in liceu nu invata decat primul an sau deloc matematica, de unde sa stie.

Numerele prime se invata in clasa a 5a, la divizibilitate ;) Deci toata lumea ar trebui sa stie ce sunt (sau ma rog.. cei care au promovat clasa a 5a).

Un numar prim reprezinta un numar natural mai mare strict decat 1 care are numai 2 divizori naturali diferiti : pe 1 si pe el insusi. Dupa cum a demonstrat Euclid in 300 ÎC, sunt un infinit de numere prime iar primele 24 sunt urmatoarele :

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89
