Is It Divisible by 4?
So, I got a quick math trick to help you guys figure out for any number if is it Divisible by 4? with 0 remainders!
This is how you do it, let’s take 5436, to figure out if this number is divisible by 4 do this:
Step 1: Is it an even number? Yes
Step 2: Take the Last number of 5436 which 6 and add it to two times the second last number which is 3. So, 6 + (3*2) = 12
Step 3: Will 4 go into 12, if you are good with multiplication tables, you would know yes it does and it will go into 12, three times with zero remainder
Therefore 4 will divide evenly into 5426, pretty cool I think so,
Hint: If you ever wanted to figure out if say 2054 is a leap year this is where the divisible by 4-speed trick would come in handy.
