11 33 66 99

Answer 1

a) 2 = 2

4 = 2^2

6 = 2*3

8 = 2^3

cmmmc = 2^3*3 = 8*3 = 24

b) 10 = 5*2

15 = 5*3

30 = 5*3*2

60 = 5*2^2*3

cmmmc = 5*3*2^2 = 60

c) 20 = 2^2*5

25 = 5^2

45 = 5*3^2

70 = 7*5*2

cmmmc = 2^2*5^2*3*7 = 4*25*21 = 100*21 = 2100

d) 11 = 11

33 = 11*3

66 = 11*3*2

99 = 11*3^2

cmmmc = 11*3^2*2 = 99*2 = 198
