Last digit ends in 0,2,4,6,8
The last digit of 1000 is 0
Since 0 is equal to 0,2,4,6,8:
then 1000 is divisible by 2
Sum of the digits is divisible by 3
The sum of the digits for 1000 is 1 + 0 + 0 + 0 = 1
Since 1 is not divisible by 3:
Then 1000 is not divisible by 3
Take the last two digits
Are they divisible by 4?
The last 2 digits of 1000 are 00
Since 00 is divisible by 4:
Then 1000 is divisible by 4
Number ends with a 0 or 5
The last digit of 1000 is 0
Since 0 is equal to 0 or 5:
Then 1000 is divisible by 5
Divisible by both 2 and 3
Since 1000 is not divisible by 2 and 3:
Then 1000 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) + 0(2) + 1(6) = 7
Since 7 is divisible by 7:
Then 1000 is divisible by 7

Since 1 is not divisible by 9:
Then 1000 is not divisible by 9
Ends with a 0
The last digit of 1000 is 0
Since 0 is equal to 0:
Then 1000 is divisible by 10
Σ odd digits - Σ even digits = 0
or 1000 is a multiple of 11
1000
1 + 0
Odd Sum = 1
1000
0 + 0
Even Sum = 0
Δ = Odd Sum - Even Sum
Δ = 1 - 0
Δ = 1
Because Δ / 11 = 90.909090909091:
Then 1000 is NOT divisible by 11
1000 is divisible by
(2,4,5,7,8,10)
