Using the clock face to know if a number is divisible by four

It's relatively easy to reckon whether a number is divisible by four if it's less than 50.
It becomes difficult when it's greater than 50, though you can use a trick of subtracting 50 from the number and see if the difference is divisible by four or not; if it is the original number is not a multiple of four.
The easier way I found is to use the clock face. Using the hour mark for numbers, those divisible by four are located at 12, 4, and 8 o'clock. If you are familiar with the clock face you instantly know 16 or 20 is a multiple of four since it positions at one of those hour marks.
Next. There's a connection between hourly marks, 12 hours around the clock and minute marks, 60 minutes around the clock. Notice the 15 minute mark, 30-minute mark, and so on coincide with 15-hour mark, 30-hour mark respectively. This fact and the fact that those divisible by four are located at particular positions on the clock face help you figure out if a number is a multiple of four.
Take, for example, number 92. Since the 90‑hour mark is at 6 o'clock position, 92 is located at 8 o'clock position, so it's easy to see it's divisible by four.
