The smallest prime number in which all of the digits are also prime is 2.The smallest multi-digit prime number in which all of the digits are also prime is 23.
Smallest is 11 & Largest is 77.
73 satisfies your condition.
You had me until "product." The product of 4 digits can't be prime.
Oh, dude, you're asking me to find prime numbers that are also into numerology? That's like asking a pineapple to do algebra. But hey, I'm up for the challenge. The prime numbers whose digits add up to 13 are 499 and 589. Just a couple of cool digits hanging out together, you know?

Prime numbers that remain prime when their digits are reversed are called emirps. Some examples of emirps include 13 (31), 17 (71), 31 (13), and 37 (73). These numbers are interesting because both the original number and its reverse are prime numbers.

A reversible prime is a number such as 37, where reversing the order of the digits gives 73 which is also a prime.

Some numbers that you can get when you reverse the digits and they are still prime numbers are: 403 ÷ 13 = 31 2,701 ÷ 37 = 73 1,207 ÷ 17 = 71
The largest known prime is (2 to the power of 43112609) -1 written out in full would take 13 million digits. The largest prime is an infinate number. it consists 12978189 digits. it is also known as "m43112609".

Yes, 347 is an emirp. An emirp is a prime number that remains prime when its digits are reversed. The reverse of 347 is 743, which is also a prime number. Therefore, both 347 and 743 are primes, confirming that 347 is indeed an emirp.
Yes, 197 is an emirp. An emirp is a prime number that remains prime when its digits are reversed. The reverse of 197 is 791, which is also a prime number. Therefore, both 197 and 791 are primes, confirming that 197 is indeed an emirp.
