Repeating Number Puzzles

The reason it always works is because 7*11*13=1001 and any 6 digit number is its original 3 digit number.
For example take 365,365 and first divide it by 7, then by 11, and at last by 13 and you will get 365, because it is like dividing the number by 1001. You can mix the order of 7, 11, and 13 because you will still get 1001 by multiplying them. Take a variable and substitute it instead of 365,365 and it will still work.
The trick or the magic number is 1001. Remember that any 6 digit number you will divide 1001 by will give you its original!
