What are the three alarm clocks ring at intervals of 4 12 20? ›

Let us take the LCM of 4, 12 and 20 using prime factorization method. LCM of these are found by looking at their divisibility by prime numbers. Thus, we found the LCM of 4, 12 and 20 to be $2\times 2\times 3\times 5=60$ . Hence, the three clocks will ring together after 60 minutes or 1 hour.

The rule is simply this: Set two alarms in the morning, three minutes apart. I call it the two-by-three rule. I'll explain why this works in a minute, but first, a few important things you should know. The second alarm should be set for whatever time you actually need to get up.

However, when an alarm clock disrupts this natural cycle, we might wake up halfway through a deep sleep phase, which can make us feel groggy and tired — even if we've slept for a good number of hours.

Interval Timer: With an Interval Timer the alarm will go off once the pre-set interval has elapsed. The interval can be set in Hours and Minutes. Example: If you set an Interval Timer for 8 hours and start it at 8:00 AM the alarms would go off at 8 AM, 4 PM and Midnight.

Four bells ring at intervals 4, 6, 8 and 14 seconds. They ring simultaneously at 12:00 O' clock. Four bells ring will ring simultaneously after 168/60 =2 min 48 sec. means at 12 hrs 2 min 48 sec.

To calculate this sum we should take the Lowest Common Multiple (L.C.M) of 6,8,12 and 18. So the bell rings simultaneously every 72 seconds. Therefore in 6 minutes i.e. 360 seconds there will be = 5 bell. Excluding the bell at the start which rung at 12 O' clock, the bell will ring 5 times in 6 minutes.
