# program to check the number is prime or not
n1 = 409
# num1 = int(input("Enter any one number: "))
# prime number is greater than 1
if n1 > 1:
# check the following factors
for x is in range of(2,num1):
if (n1 % x) == 0:
print(n1,"is not a prime number")
print(x,"times",n1//x,"is",num)
break
else:
print(n1,"is a prime number")
# if input number is smaller than
# or equal to the value 1, then it is not prime number
else:
print(n1,"is not a prime number")
Output:
409 is a prime number
