\[\boxed{\mathbf{141\ (141).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
Пояснение.
Решение.
\[1)\ 72 = 2^{3} \cdot 3^{2};\ \ \ 120 = 2^{3} \cdot 3 \cdot 5\]
\[НОД\ (72;120) = 2^{3} \cdot 3 =\]
\[= 8 \cdot 3 = 24\]
\[2)\ 792 = 2^{3} \cdot 3^{2} \cdot 11;\ \ \ 1188 =\]
\[= 2^{2} \cdot 3^{3} \cdot 11\]
\[НОД\ (792;1188) =\]
\[= 2^{2} \cdot 3^{2} \cdot 11 = 4 \cdot 9 \cdot 11 = 396\]
\[3)\ 924 = 2^{2} \cdot 3 \cdot 7 \cdot 11;\ \ \ 396 =\]
\[= 2^{2} \cdot 3^{2} \cdot 11\]
\[НОД\ (924;396) = 2^{2} \cdot 3 \cdot 11 =\]
\[= 4 \cdot 33 = 132\]
\[4)\ 116 = 2^{2} \cdot 29;\ \ \ 111 = 3 \cdot 37\]
\[НОД\ (116;\ 111) = 1\]
\[\boxed{\mathbf{141}.}\]
