All the even numbers and the odd multiples of 5.
The number 1 itself has a prime factorization of just the number 1. All other numbers have a prime factorization consisting of at least two prime numbers.
1 & 59... 59 is a prime number !
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
27 = 128
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.
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.
91 cannot be in the prime factorization of any number because it is not a prime number itself.
421 is a prime number so it does not have prime factorization.
19 is a prime number, so it has no prime factorization.
That's the prime factorization of 945.
