Answer: 97 is: the 25th prime number (the largest two-digit prime number in base 10), following 89 and preceding 101. a Proth prime as it is 3 × 25 + 1.
What is the greatest factor of smallest two-digit number?
The smallest two-digit number is 10 and greatest two-digit number is 99. In a two-digit number, one digit is placed at ten’s place and the other at one’s place. Given only two digits, we can form only two different two-digit numbers.
What two-digit number has exactly $9$ Factors?

Have a look! The smallest 2-digit number is 10 and the greatest 2-digit number is 99.
What does it mean to do prime factorization?
What is Prime Factorization? Factorization means that you break a number into its factors. To do Prime Factorization, after you break your number into factors, you break the factors into factors, then you break the factors of the factors into factors, and so forth and so on, until you’ve only got prime numbers left.
How many 2 digit numbers have exactly 3 factors?

When do you factor a number with lots of factors?
When you’re factoring a number with lots of factors it feels that this is the kind of question with lots of answers, but the Unique Factorization Theorem says that it’s not. Even though there’s lots of ways to do the prime factorization, the theorem says that no matter what arbitrary choices you make, you’ll get the same answer in the end.
