lcm(12,15,18)
12=2*2*3
15=3*5
18=2*3*3
LCM=4*9*5=180mins
1hr=60mins
? hr=180mins
?hrs=180/60
?hrs=3
hence after 3 hrs they will together ring.
10.30+3.00 hrs=1.30pm
12=2*2*3
15=3*5
18=2*3*3
LCM=4*9*5=180mins
1hr=60mins
? hr=180mins
?hrs=180/60
?hrs=3
hence after 3 hrs they will together ring.

Step-by-step explanation:
L.C.M of 12, 15 and 18 = 180
1 hr = 60 min
= 180/60
= 3 hr
The bell will ring together again at 1:30 p.m
