1.

216 = 2 * 2 * 2 * 3 * 3 * 3,

154 = 2 * 7 * 11,

91 = 7 * 13,

396 = 2 * 2 * 3 * 3 * 11, значит:

НОК (216, 154, 99, 396) = 2 * 2 * 2 * 3 * 3 * 3 * 7 * 11 * 13 = 216216,

216216 - общий знаменатель:

1/216 = 1001/216216 9/154 = 12636/216216,

7/91 = 16632/216216,

55/396 = 30030/216216,

2.

32 = 2 * 2 * 2 * 2 * 2,

48 = 2 * 2 * 2 * 2 * 3,

80 = 2 * 2 * 2 * 2 * 5,

112 = 2 * 2 * 2 * 2 * 7, значит:

НОК (32, 48, 80, 112) = 2 * 2 * 2 * 2 * 2 * 3 * 5 * 7 = 3360,

3360 - общий знаменатель,

1/32 = 105/3360,

1/48 = 70/3360,

3/80 = 126/3360,  

5/112 = 150/3360
