1. Sum of digits (12) is divisible by 3, so number is divisible by 3
2. It's an even number so it's divisible by 2
3. If it's divisible by both 3 and 2 then it's divisible by 3 x 2, ie 6.

How can you tell without dividing that a number is divisible by 8?
There is not an easy way without some division. The simplest is to check the divisibility of the number formed by the last three digits.
How can you tell if a number can be exactly divided by eight?
You can tell if the last 2 digits of the number can be divisible by 4 or 8. So the number 3156372856374856386578365864would be divisible by 8 because 8 can go into 64.
Is 414 equally divisible by 3?
I think the question is mistyped, and should be "Is 414 evenly divisible by 3?" i.e. does it divide by 3 without leaving a remainder. The answer is yes. A quick way to tell if a number is divisible by 3 is to add the digits and if the total is divisible by 3, then the number in question is also divisible by 3 4 + 1 + 4 = 9 and 9 is divisible by 3 414 ÷ 3 = 138

How you can tell that 136 isn't in this sequences 3 6 9 12?
Because it's not exactly divisible by 3.
How can you do divisibles without dividing?
If you know the rules of divisibility, you can tell if a number is divisible by another number by looking at it. A number is divisible... by 2 if it's even. by 3 if the sum of its digits is a multiple of 3. by 4 if the last two digits are a multiple of 4. by 5 if it ends in a 5 or 0. by 6 if it's divisible by 2 and 3. by 8 if the last three digits are divisible by 8. by 9 if the sum of its digits is a multiple of 9. by 10 if it ends in a 0. There is a rule for 7, but it's annoyingly complicated, hard to remember and takes as long to implement as actually dividing by 7.
