D:6=104 rest 1,3,5;
D=104×6+1;
D=624+1;
D=625;
D=104×6+3;
D=627;
D=104×6+5;
D=629;
restul poate fi 1 , 3 , 5
a : 6 = 104 rest 1
a = 6 x 104 + 1
a = 624 + 1 = 625
a : 6 = 104 rest 3
a = 6 x 104 + 3
a = 624 + 3
a = 627
a : 6 = 104 rest 5
a = 6 x 104 + 5
a = 624 + 5
a = 629
a : 6 = 104 rest 1
a = 6 x 104 + 1
a = 624 + 1 = 625
a : 6 = 104 rest 3
a = 6 x 104 + 3
a = 624 + 3
a = 627
a : 6 = 104 rest 5
a = 6 x 104 + 5
a = 624 + 5
a = 629
