Giải:
a) \(BCNN\left(10;12\right)\)
\(10=2.5\)
\(12=2^2.3\)
\(\Rightarrow BCNN\left(10;12\right)=2^2.3.5=60\)
b) \(BCNN\left(24;10\right)\)
\(24=2^3.3\)
\(10=2.5\)
\(\Rightarrow BCNN\left(24;10\right)=2^3.3.5=120\)
c) \(BCNN\left(33;44;55\right)\)
\(33=3.11\)
\(44=2^2.11\)
\(55=5.11\)
\(\Rightarrow BCNN\left(33;44;55\right)=2^2.3.5.11=660\)
d) \(BCNN\left(4;14;26\right)\)
\(4=2^2\)
\(14=2.7\)
\(26=2.13\)
\(\Rightarrow BCNN\left(4;14;26\right)=2^2.7.13=364\)
e) \(BCNN\left(8;18;30\right)\)
\(8=2^3\)
\(18=2.3^2\)
\(30=2.3.5\)
\(\Rightarrow BCNN\left(8;18;30\right)=2^3.3^2.5=360\)
g) \(BCNN\left(6;8;10\right)\)
\(6=2.3\)
\(8=2^3\)
\(10=2.5\)
\(\Rightarrow BCNN\left(6;8;10\right)=2^3.3.5=120\)
