I would like to explain this with an example
Save the regular interval of alarms are 15 and 48 seconds so both alarms rings together after x seconds where X is LCM of 50 and 48 LCM of 50 and 48 is 1200 so both alarms ring together after 1200 seconds are both alarm rings together after 20 minutes
Add edit question the LCM of 4 and 10 seconds is 20 so they both will be together after 20 seconds
Plz vote if you like or understand the answer
