On the Subject of Prime Time

The bomb is now primed and ready.

This module has a button with a display. To disarm the module press it at specific times for each stage. Note: a strike will reset all stages.

Stage 1

The display is empty. Press the button when the total amount of seconds remaining is a prime number.

Stage 2

The display contains a prime number. Press the button when the total amount of seconds remaining is a multiple of this displayed prime number.

Stage 3

The display cycles between three primes. Press the button when the total amount of seconds remaining is a multiple of this displayed prime number. Repeat until all the primes given have been divisors exactly once. Multiple primes can be done at once (you could do all of them at once even), however if a prime has already been a divisor before during this stage, the module will strike.
