Verified answer

1) 25 = 5 * 5

  15 = 3 * 5

  5 = 5

НОК (5; 15; 25) = 5 * 5 * 3 = 75

2) 32 = 2 * 2 * 2 * 2 * 2

   24 = 2 * 2 * 2 * 3

   16 = 2 * 2 * 2 * 2

НОК (16; 24; 32) = 2 * 2 * 2 * 2 * 2 * 3 = 96

3) 72 = 2 * 2 * 2 * 3 * 3

   60 = 2 * 2 * 3 * 5

НОК (60; 72) = 2 * 2 * 2 * 3 * 3 * 5 = 360

4) 162 = 2 * 3 * 3 * 3 * 3

   108 = 2 * 2 * 3 * 3 * 3

НОК (108; 162) = 2 * 3 * 3 * 3 * 3 * 2 = 324
