Any number that is the 6th power of a prime integer.
A number that has exactly two (positive) factors is called a prime number. For instance, the only factors of 7 are 1 and 7.
It is 2^6 = 64.
The largest two-digit number with exactly three factors is 99. A number has exactly three factors if it is the square of a prime number, specifically in the form ( p^2 ) where ( p ) is a prime. The only prime number whose square is a two-digit number is 7, since ( 7^2 = 49 ) and ( 11^2 = 121 ) exceeds two digits. Thus, 49 is the largest two-digit number with exactly three factors.
