Any power of 2
The only number with that prime factorization has to be 48.
Yes. Any prime number greater than 100 has only itself in its prime factorization. Examples: The prime factorization of 101 is 101. The prime factorization of 109 is 109. The prime factorization of 127 is 127. The prime factorization of 311 is 311. The prime factorization of 691 is 691.
Prime Factorization of 22 is a prime number, so it does not have a prime factorization.
Only 23 has prime factorization of 23.
There is only one prime factorization string for each number, so there is not a "longest" one. Since 239 is a prime number, its prime factorization is 239.
11 is a prime number. Its only prime factor is 11.
There is no prime factorization of 47 since it is a prime number. It's only factors are 1 and 47.
Only if they're the same number. Every composite number has a unique prime factorization.
