code to check for prime number code example
Example 1: python is a number prime
def prime(n):
if min(n//3,n//2,n//5) == 0:
return True
elif min(n%3,n%2,n%5) == 0:
return False
else:
return True
# Super easy to use, and maximum efficiency! No imports needed.
print(prime(732))
def divis(n):
if prime(n) == True:
return (1,n)
for i in [2,3,5]:
if n%i == 0:
return (i,n/i)
print(divis(735))
# Gets a divisibility pair: Make sure you have also implemented prime() or it may not work.
Example 2: Write a function to check if a number is prime?
#include
int main() {
int n, i, flag = 0;
printf("Enter a positive integer: ");
scanf("%d", &n);
for (i = 2; i <= n / 2; ++i) {
// condition for non-prime
if (n % i == 0) {
flag = 1;
break;
}
}
if (n == 1) {
printf("1 is neither prime nor composite.");
}
else {
if (flag == 0)
printf("%d is a prime number.", n);
else
printf("%d is not a prime number.", n);
}
return 0;
}
