Divisor 20848

To determine if any number is divisible by 20848, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 16 and 1303 - then it is divisible by 20848.

The following tests must pass:

• Test if a number is divisible by 16
• The "Alex Guichet Test" for Divisibility by 1303
