Not all two-digit numbers are prime. A prime number is defined as a number greater than one that has no positive divisors other than one and itself. While there are several two-digit prime numbers, such as 11, 13, and 17, many two-digit numbers, like 10, 12, and 14, are composite because they have divisors other than one and themselves.
The largest single digit prime is '7' The largest two digit prime is '97'. Their product is 97 X 7 = 679.
