Explicație pas cu pas:
a) a = 6 ; b = 15 ; 0 < m < 100
cmmmc (a,b) = 2·3·5 = 30
a = 2·3 ; b = 3·5
m = {30 ; 60 ; 90}
-----------------------------
b) a = 20 ; b = 70 ; m ≠ 0 ; m ≤ 280
a = 2²·5 ; b = 2·5·7 => cmmmc (a,b) = 2²·5·7 = 140
m = {140 ; 280}
----------------------------
c) a = 28 ; b = 14 ; m ≠ 0 ; m = minim
a = 2²·7 ; b = 2·7 => cmmmc (a,b) = 2²·7 = 28
=> m = 28
-----------------------------
d) a = 75 ; b = 50 ; m ≠ 0 ; m = minim
a = 5²·3 ; b = 5²·2 =>
cmmmc (a,b) = 5²·2·3 = 150 =>
m = 150
