All the even numbers and the odd multiples of 5.
If the number is even, there will be at least one 2 in the prime factorization. If the number is odd, there won't be any twos.
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?
Prime Factorization of 3131 is a prime number, so there is no prime factorization of it.It is 31 because it is a prime number
Prime Factorization of 22 is a prime number, so it does not have a prime factorization.
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.
12 is not a prime factorization.
421 is a prime number so it does not have prime factorization.
When all the factors are prime numbers, that's a prime factorization.
19 is a prime number, so it has no prime factorization.
