Answer:
a) 76,24
76 = 2*2*19
24 = 2*2*2*3
lcm = 2*2*19*6 = 456
b) 18,20
18 = 2*3*3
20=2*2*5
lcm = 2*3*3*2*5 = 180
c) 10 , 18
10 = 2*5
18 = 2*3*3
lcm = 2*3*3*5 = 90
d) 15,35
15 = 3*5
35= 5*7
lcm = 3*5*7 = 105
e) 25,30
25 = 5*5
30= 2*3*5
lcm = 2*3*5*5 = 150
f) 18,32
18=2*3*3
32=2*2*2*2*2
lcm = 2*2*2*2*2*3*3 = 288
g) 10,15,20
10=2*5
15=3*5
20=2*2*5
lcm= 2*2*3*5 = 60
h) 16,12,32
16 = 2*2*2*2
12 = 2*2*3
32=2*2*2*2*2
lcm = 2*2*2*2*2*3 = 96
