is 4021 prime

No, 4021 is not a prime number. A prime number is a whole number greater than 1 that is divisible only by 1 and itself. 4021 is divisible by 17, which is a number other than 1 and itself, so it is not considered to be a prime number.

For the curious, 4021 is not divisible by 17.

I guess I only tried the first few single digit primes. Fair enough!
