Answer 1

Answer:

a) 315

b) 1344

c) 180

d) 315

Step-by-step explanation:

a) 21, 63, 195

21 = 3 x 7

63 = 3 x 3 x 7

105 = 3 x 5 x 7

LCM = 3 x 3 x 5 x 7

LCM = 315

b) 64, 96, 112

64 = 2 x 2 x 2 x 2 x 2 x 2

96 = 2 x 2 x 2 x 2 x 2 x 3

112 = 2 x 2 x 2 x 2 x 7

LCM = 2 x 2 x 2 x 2 x 2 x 2 x 3 x 7

LCM = 1344

c) 12, 18, 90

12 = 2 x 2 x 3

18 = 2 x 3 x 3

90 = 2 x 3 x 3 x 5

LCM = 2 x 2 x 3 x 3 x 5

LCM = 180

d) 45, 35, 21

45 = 3 x 3 x 5

35 = 5 x 7

21 = 3 x 7

LCM = 3 x 3 x 5 x 7

LCM = 315
