Examples on LCM of 12 and 18
Example 1: Two measuring rods are 12 cm and 18 cm in length. What is the least length of a rope that can be measured by the full length of each of these rods?
Solution:
The least length of rope that can be measured by the full length of each of these rods is the least common multiple (LCM) of their lengths.
The LCM of 12 and 18 is 36.
So, the least length of rope that can be measured is 36 cm.
Example 2: Two bells toll at intervals of 12 mins and 18 mins. If they start tolling together, after what time will they next toll together?
Solution:
To find when the bells will next toll together, we need to find the least common multiple (LCM) of their tolling intervals, which are 12 minutes and 18 minutes.
The LCM of 12 and 18 is 36. So, the bells will next toll together after 36 minutes.
