This is a sample program I wrote to check if a number is prime or not. def is_prime(x): y=0 if x<=1: return False elif x == 2: return True elif x%2==0: return False else: root = int(x**.5)+2 for i in xrange (2,root): if x%i==0: return False y=1 if y==...
What you gave is not about primality test but prime factorization. @VishnuDasu –Kazi Ziaul Hassan Commented Jun 25, 2019 at 13:07 You can easily modify the code to determine whether the number is prime or not. One simple way is to just count the number of factors. Complex...
Euler first examines the number 1000009 and then 1000081. Obviously 1000009=1000^2+3^2, and then he finds that 1000009=972^2+235^2, hence it is not prime. On the other hand, Euler finds that 1000081 can be written as a sum of squares in only one way, hence it is prime....

Write a function to check if a number is prime or not. A number is prime if it has only two distinct divisors: 1 and itself. For instance, numbers like 2, 3, 5, and 7 are all prime. If the number is prime, return "It's a prime number". Otherwise, return "It's not a prime...
