Ответ:

1) делители 30:

1, 2, 3, 5, 6, 10, 15, 30

2) делители 12:

1, 2, 3, 4, 6, 12

3) делители 23:

1, 23

4) делители 72:

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Пошаговое объяснение:

1) делители 30:

1, 2, 3, 5, 6, 10, 15, 30

$\frac{30}{1} = 30\\\\\frac{30}{2} = 15\\\\\frac{30}{3} = 10\\\\\frac{30}{5} = 6\\\\\frac{30}{6} = 5\\\\\frac{30}{10} = 3\\\\\frac{30}{15} = 2\\\\\frac{30}{30} = 1\\$

2) делители 12:

1, 2, 3, 4, 6, 12

$\frac{12}{1} = 12\\\\\frac{12}{2} = 6\\\\\\frac{12}{3} = 4\\\\\frac{12}{4} = 3\\\\\frac{12}{6} = 2\\\\\frac{12}{12} = 1$

3) делители 23:

1, 23

$\frac{23}{1} = 23\\\\\frac{23}{23} = 1$

4) делители 72:

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

$\frac{72}{1} = 72\\\\\frac{72}{2} = 36\\\\\frac{72}{3} = 24\\\\\frac{72}{4} = 18\\\\\frac{72}{6} = 12\\\\\frac{72}{8} = 9\\\\\frac{72}{9} = 8\\\\\frac{72}{12} = 6\\\\\frac{72}{18} = 4\\\\\frac{72}{24} = 3\\\\\frac{72}{36} = 2\\\\\frac{72}{72} = 1$
