Answer
(i) 68
68 = 1 × 68
68 = 2 × 34
68 = 4 × 17
Hence, factors of 68 are 1, 2, 4, 17, 34 and 68.
(ii) 27
27 = 1 × 27
27 = 3 × 9
Hence, factors of 27 are 1, 3, 9 and 27.
(iii) 210
210 = 1 × 210
210 = 2 × 105
210 = 3 × 70
210 = 5 × 42
210 = 6 × 35
210 = 7 × 30
210 = 10 × 21
210 = 14 × 15
Hence, factors of 210 are 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105 and 210.
