Last digit ends in 0,2,4,6,8
The last digit of 200 is 0
Since 0 is equal to 0,2,4,6,8:
then 200 is divisible by 2
Sum of the digits is divisible by 3
The sum of the digits for 200 is 2 + 0 + 0 = 2
Since 2 is not divisible by 3:
Then 200 is not divisible by 3
Take the last two digits
Are they divisible by 4?
The last 2 digits of 200 are 00
Since 00 is divisible by 4:
Then 200 is divisible by 4
Number ends with a 0 or 5
The last digit of 200 is 0
Since 0 is equal to 0 or 5:
Then 200 is divisible by 5
Divisible by both 2 and 3
Since 200 is not divisible by 2 and 3:
Then 200 is not divisible by 6
Multiply each respective digit by 1,3,2,6,4,5
Work backwards
Repeat as necessary
0(1) + 0(3) + 2(2) = 5
Since 5 is not divisible by 7:
Then 200 is not divisible by 7

Σ odd digits - Σ even digits = 0
or 200 is a multiple of 11
200
2 + 0
Odd Sum = 2
200
0
Even Sum = 0
Δ = Odd Sum - Even Sum
Δ = 2 - 0
Δ = 2
Because Δ / 11 = 18.181818181818:
Then 200 is NOT divisible by 11
200 is divisible by
(2,4,5,8,10)
