Explicație pas cu pas:
a) cmmdc (2, 4, 6, 10) = 2
2 = 2 ; 4 = 2² ; 6 = 2·3 ; 10 = 2·5
cmmmc(2,4,6,10) = 2²·3·5 = 60
b) cmmdc (30, 48, 72) = 2·3 = 6
30 = 2·3·5 ; 48 = 2⁴·3 ; 72 = 2³·3²
cmmmc(30,48,72) = 2⁴·3²·5
c) cmmdc (121, 132, 1111) = 11
121 = 11² ; 132 = 11·2²·3 ; 1111 = 11·101
cmmmc(121 , 132 , 1111) = 11²·2²·3·101 = 146652
d) cmmdc (115, 46, 529) = 23
115 = 5·23 ; 46 = 2·23 ; 529 = 23²
cmmmc(115,46,529) = 23²·2·5 = 5290
e) cmmdc (50, 63, 143) = 1
50 = 2·5² ; 63 = 7·3² ; 143 = 11·13
cmmmc(50,63,143) = 50·63·143 = 450450
f) cmmdc (120, 300, 240, 400) =2²·5 = 20
120 = 2³·3·5 ; 300 = 3·2²·5² ; 240 = 2⁴·3·5 ; 400 = 2⁴·5²
cmmmc(120,300,240,400) = 2⁴·3·5² = 1200
