Răspuns: 13 -> impartitorul
Explicație pas cu pas:
48 - 9 = 39
54 - 2 = 52
__________
39 = 3 × 13
52 = 2² × 13
__________
c.m.m.d.c al numerelor 39 si 52 = 13 -> impartitorul

Verific:
48 : 13 = 3 rest 9
54 : 13 = 4 rest 2
48 : n = c1 r 9 => n = ( 48 - 9 ) : c1 = 39 : c1
54 : n = c2 r 2 => n = ( 54 - 2 ) : c2 = 52 : c2
39 = 3 × 13
52 = 2 ^ 2 × 13
c.m.m.d.c = 13
n = 13
