A) 24 : 1, 2, 3, 4, 6, 8, 12, 24
36 : 1, 2, 3, 4, 6, 9, 12, 18, 36

PGCD ( 36 ; 24 ) = 12

b) 20 : 
1, 2, 4, 5, 10, 20
63 : 
1, 3, 7, 9, 21, 63

PGCD ( 63 ; 20 ) = 1

c) 72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
1 : 1

PGCD ( 72 ; 1 ) = 1

d) 434 : 
1, 2, 7, 14, 31, 62, 217, 434
98 : 
1, 2, 7, 14, 49, 98

PGCD ( 434 ; 98 ) = 14

e) 168 : 
1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
42 : 
1, 2, 3, 6, 7, 14, 21, 42

PGCD ( 168 ; 42 ) = 42

f) 124 : 
1, 2, 4, 31, 62, 124
0 : 0

PGCD ( 124 ; 0 ) = Normalement, c'est 0 mais j'ai un doute, désolé.
