Question

Aflati cel mai mic numar natural care impartit la 16 si 40 ne da de fiecare data restul 3

Answer 1

x=nr. necunoscut

x÷16=a, rest 3⇒x=16a+3⇒x-3=16a                                 
x÷40=b, rest 3⇒x=40b+3⇒x-3=40a                                  

⇒x-3=[16;40]⇒ x-3=80⇒x=83
c.m.m.m.c. a numerelor 16 si 40=80
