Question

16) Write all the factors of (i) 15 (ii) 36 (iii) 60 (iv) 75​

Answer 1

Answer:

(i) Factors of 15 = 1, 3, 5 and 15

(ii) 36

36 = 1 × 36

36 = 6 ×6

36 = 9 × 4

36 = 12 × 3

36 = 18 × 2

Hence the factors are 1, 2, 3, 4, 6, 9,12,18 and 36

(iii) 60

60 = 1 × 60

60 = 10 × 6

60 = 30 × 2

60 = 15 × 4

60 = 12 × 5

60 = 3 × 20

Hence the factors are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60

iv) 75

75 = 1 × 75

75 = 3 × 25

75 = 5 × 15

Hence the factors are 1, 3, 5, 15, 25 and 75
