Решение:
Найдём наибольший общий делитель (НОД) и наименьшее общее кратное (НОК) для заданных пар чисел.
- НОД(60; 128):
60 = 2 \(\cdot\) 2 \(\cdot\) 3 \(\cdot\) 5 = 22 \(\cdot\) 3 \(\cdot\) 5
128 = 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 2 = 27
НОД(60; 128) = 22 = 4 - НОД(312; 48):
312 = 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 3 \(\cdot\) 13 = 23 \(\cdot\) 3 \(\cdot\) 13
48 = 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 3 = 24 \(\cdot\) 3
НОД(312; 48) = 23 \(\cdot\) 3 = 8 \(\cdot\) 3 = 24 - НОК(33; 88):
33 = 3 \(\cdot\) 11
88 = 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 11 = 23 \(\cdot\) 11
НОК(33; 88) = 23 \(\cdot\) 3 \(\cdot\) 11 = 8 \(\cdot\) 3 \(\cdot\) 11 = 264 - НОД(28; 142):
28 = 2 \(\cdot\) 2 \(\cdot\) 7 = 22 \(\cdot\) 7
142 = 2 \(\cdot\) 71
НОД(28; 142) = 2 - НОК(100; 175):
100 = 2 \(\cdot\) 2 \(\cdot\) 5 \(\cdot\) 5 = 22 \(\cdot\) 52
175 = 5 \(\cdot\) 5 \(\cdot\) 7 = 52 \(\cdot\) 7
НОК(100; 175) = 22 \(\cdot\) 52 \(\cdot\) 7 = 4 \(\cdot\) 25 \(\cdot\) 7 = 700 - НОК(16; 72):
16 = 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 2 = 24
72 = 2 \(\cdot\) 2 \(\cdot\) 2 \(\cdot\) 3 \(\cdot\) 3 = 23 \(\cdot\) 32
НОК(16; 72) = 24 \(\cdot\) 32 = 16 \(\cdot\) 9 = 144
Ответ: НОД(60;128)=4; НОД(312;48)=24; НОК(33;88)=264; НОД(28;142)=2; НОК(100;175)=700; НОК(16;72)=144.
