Explicație pas cu pas:
(a, b) = 14
Fie x, y a.i. (x, y) = 1 si a = 14x ; b = 14y
a + b = 98
14x + 14y = 98 | ÷14
x + y = 7
(x, y) apartine {(0, 7), (1, 6), (2, 5), (3, 4)} si invers
dar (x, y) = 1 => (x, y) apartine {(1, 6), (2, 5), (3, 4)} si invers
deci (a, b) apartin {(14, 84), (28, 70), (42, 56)} si invers
