求質數法



判斷n是否為質數 時，將n除以n以下的整數直至2為止，以觀察n能

除盡，這時如有被除盡的數，便被視為非質數而脫離出回圈。到了最後如無除盡的數，則此數即為質數。-Seeking qualitative method to determine whether the prime number n to determine whether the prime number n will be n divided by n integers until 2 the following date, in order to observe the n can be divisible, then if there were a number divisible, it is considered non-prime number and out of the loop. At the end of a few such as non-divisible, then the number is prime number.
