                           i.          12, 15 and 21

                         ii.          17, 23 and 29

                       iii.          8, 9 and 25

​

Answer 1

Answer:

(i)

12 = 2×2×3.

15 = 3×5.

21 = 3×7.

LCM = 3×2×2×5×7 = 420.

HCF = 3.

(ii)

17 = 1×17.

23 = 1×23.

29 = 1×29.

LCM = 11339.

HCF = 1.

(iii)

8 = 2×2×2.

9 = 3×3.

25 = 5×5.

LCM = 1800.

HCF = 1.
