Answer:

A.) the LCM of 10, 15, and 6 is 30

10 = 2 × 5

15 = 3 × 5

6 = 2 × 3

LCM (10, 15, 6)

= 2 × 3 × 5

= 30

B.) the LCM of 16, 12, 18 is 144

16 = 2 × 2 × 2 × 2

12 = 2 × 2 × 3

18 = 2 × 3 × 3  

LCM(16, 12, 18)

= 2 × 2 × 2 × 2 × 3 × 3

= 144

C.) the LCM of 25,30,40 is 600

25 = 5 × 5

30 = 2 × 3 × 5

40 = 2 × 2 × 2 × 5

LCM(25, 30, 40)

= 2 × 2 × 2 × 3 × 5 × 5

= 600
