Answer:

1. Lcm is 3

2.Lcm is 4368

3. Lcm is 6160

Answer 2

(I) 42,63,162

42=2*3*7

63=3*3*7

162=2*3*3*33

L. C. M=2*3*3*3*3*7=1134

(II) 42,78,104,112

42=2*3*7

78=2*13*3

104=2*2*2*13

112=2*2*2*2*7

L. C. M= 2*2*2*2*3*7*13=2068

(III) 16,28,40,77

16=2*2*2*2

28=2*2*7

40=2*2*2*5

77=7*11

L. C. M= 2*2*2*2*5*7*11=6160
