# Q. Find the HCF of the following: (i) 24 and 36         (ii) 15, 25 and 30 (iii) 8 and 12         (iv) 12, 16 and 28

(i) 24 and 36

24 = 2 $\times$ 2 $\times$ 2 $\times$ 3

36 = 2 $\times$ 2$\times$ 3 $\times$ 3

HCF = 2 $\times$ 2 $\times$ 3 = 12

(ii) 15, 25 and 30

15 = 3 $\times$

25 = 5 $\times$

30 = 2 $\times$ 3 $\times$ 5

HCF = 5

(iii) 8 and 12

8 = 2 $\times$ 2 $\times$ 2

12 = 2 $\times$ 2 $\times$ 3

HCF = 2 $\times$ 2 = 4

(iv) 12, 16 and 28

12 = 2 $\times$ 2 $\times$

16 = 2 $\times$ 2 $\times$ 2 $\times$ 2

28 = 2 $\times$ 2 $\times$ 7

HCF = 2 $\times$ 2 = 4
