Answer 1

a. D10∩D36={1; 2; 5; 10}∩{1; 2; 3; 4; 6; 8; 12; 18; 36}={1; 2}
b. D24∩D36={1; 2; 3; 4; 6; 8; 12; 24}∩D36={1; 2; 3; 4; 6; 8; 12}
c. D35∩D40={1; 5; 7; 35}∩{1; 2; 4; 5; 8; 10; 20; 40}={1; 5}
d. D18∩D3={1; 2; 3; 6; 9; 18}∩{1; 3}={1; 3}
e. D16∩D34={1; 2; 4; 8; 16}∩{1; 2; 17; 34}={1; 2}
f. M5∩M6={0; 5; 10; 15; 20; 25; 30.....}∩{0; 6; 12; 18; 46; 30....}=M30
g. M3∩M6=M6
h.M6∩M9∩M12=M36 (36 este cel mai mic multiplu comun al nr 6, 9 si 12)
