Every prime number has exactly 2 factors, 1 and the number itself.
it should just have 2 numbers
i believe, there can only be one.
Prime factorizations, for one example.
Prime factorizations are unique. If you change the prime factorization, you change the number.
Prime numbers only have one prime factor. Prime factorizations have at least two. Sometimes they're the same number (2 x 2 = 4) so we could say it has one distinct prime factor.
No. Any factor string of a negative number would have to include at least one negative number and there aren't any negative prime numbers.
There are infinitely many possible answers. One such is 1001 = 7*11*13
Apart from the order of the factors, prime factorisation of any number is unique so there can be only one answer. 55 = 5 * 11
61 and 73 are both prime numbers. Prime numbers don't have prime factorizations since they only have one prime factor. The GCF of any set of different prime numbers is 1, since they don't have any prime factors in common.
To solve prime factorizations, divide a composite number by prime numbers until all the factors are prime. Many people like to use a chart of some kind to help visualize the process. One kind is a factor tree. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. 2 x 3 x 5 x 7 is the prime factorization of 210.
Since prime numbers only have one prime factor (themselves), they don't have prime factorizations.
