Пояснение.
Решение.
\[1)\ 8 = 2^{3};\ \ 12 = 2^{2} \cdot 3\]
\[НОК(8;12) = 2^{3} \cdot 3 = 24.\]
\[2)\ 12 = 2^{2} \cdot 3;\ \ 16 = 2^{4}\]
\[НОК(12;16) = 2^{4} \cdot 3 = 48.\]
\[3)\ 6 = 2 \cdot 3;\ \ \ 12 = 2^{2} \cdot 3\]
\[НОК(6;12) = 2^{2} \cdot 3 = 12.\]
\[4)\ 10 = 2 \cdot 5;\ \ \ 21 = 3 \cdot 7\]
\[НОК(10;21) = 2 \cdot 3 \cdot 5 \cdot 7 =\]
\[= 210.\]
\[5)\ 24 = 2^{3} \cdot 3;\ \ \ 36 = 2^{2} \cdot 3^{2}\]
\[НОК(24;36) = 2^{3} \cdot 3^{2} = 72.\]
\[6)\ 6 = 2 \cdot 3;\ \ \ 8 = 2^{3};\ \ \ 12 =\]
\[= 2^{2} \cdot 3\]
\[НОК(6;8;12) = 2^{3} \cdot 3 = 24.\]
\[\boxed{\mathbf{163}.}\]
\[1)\ 364 = 2^{2} \cdot 7 \cdot 13;\ \ \ \]
\[495 = 3^{2} \cdot 5 \cdot 11\]
\[НОД(364;495) = 1\]
\[Взаимно\ простые.\]
\[2)\ 380 = 2^{2} \cdot 5 \cdot 19;\ \ \ \ \]
\[399 = 3 \cdot 7 \cdot 19\]
\[НОД(380;399) = 19\]
