The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
The prime factorization for 72 is in the following 2.2.2.3.3=72
53 is a prime number so there is no relevant prime factorization for it.
The only number with that prime factorization has to be 48.
91 cannot be in the prime factorization of any number because it is not a prime number itself.
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.
When all the factors are prime numbers, that's a prime factorization.
421 is a prime number so it does not have prime factorization.
19 is a prime number, so it has no prime factorization.
Since 89 is a prime number, the prime factorization of the number is simply 89.
That's the prime factorization of 945.
23 is a prime number and does not require factorization.
