Divisor 1253

To determine if any number is divisible by 1253, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 179 - then it is divisible by 1253.

The following tests must pass:

• Test if a number is divisible by 7
• Test if a number is divisible by 179

Easy!
