The number is 397.
it is a pin number to stop people finding out personal details
You know when to stop testing when the program works well enough.
There is no simple pattern or rule for finding primes. The only certain way is to start with 2 and eliminate all multiples of 2. Then move to the next number on the list (3) and eliminate all numbers that are its multiples, and then the next number in the list. Stop after you have done the largest integer in the list which is less than or equal to the maximum number of your range.In this case, sqrt(50) = 7.07 so stop after doing 7 and its multiples.
Finding out new ideas is very salutary. Why does church have to stop that?

the fallen in transformers revenge of the fallen is one of the seven primes. the primes were the first transformers that were created. the fallen and the other primes were searching all over the Galaxy for energon. the energon harvester would destroy the sun to harvest the energon. the primes set out with one rule. never destroy a planet with life on it (the sun would destoy the planet). the fallen wanted to break that rule but the other primes managed to stop him. but he survived and his name became the fallen.
yes if we work hard enough we can
finding a cure
The current laws regarding animal testing are that the animal testing must be carefully reviewed and overseen. There are several laws regulating the use of animals for testing.
Dunno about Linux, but I've written mine in C.It prime factorises the numbers, making a note of the highest power of each prime factor as it goes (in a linked list of malloc()ed structures). Once all the numbers have been factorised, it has a list of all the primes used along with their highest power. The lcm is then the product of the primes raised to their highest power.You are also not limited to the lcm of 2 numbers - you can keep factorising numbers until you run out of them and find the lcm of them all!Whilst you're at it you can add finding their hcf very easily: this time it's the product of the common primes to their lowest power.All that is then needed is the prime factorisation of the numbers.The normal method is:try the first prime (2)If it does not divide the number: set the prime to the next primeTry again from step 2Add one to the power count of this primereplace the number by the number divided by the primeif the number is not 1 go back to step 2Found all primes, stop!Finding the primes by which to divide is not easy on the fly, so you could check 2 specifically and then all odd numbers 3, 5, 7,..., but an improvement is to specifically check 2 and 3 and then check the numbers 6n ± 1 (which may be prime and why are 6n, 6n ± 2 and 6n ± 3 definitely not prime?) which skips every third odd number - this sequence of potential primes (5, 7, 11, 13, 17, 19, ...) can be easily generated.And while you're at it, you could display the prime factorisation you've done.And using that prime factorisation you can list the factors (and factor pairs) for the numbers.Obviously you'll need to sort out how the numbers are input to the program - I decode argv[], but you could use reading from stdin if you prefer.
You should stop smoking immediately after finding out you are pregnant.
