It is in a class called "units" since it is neither prime nor composite.
No 1 it is not a prime number. The definition of a prime number is that it can only have factors of one and itself. Since one already has one then it can not be a prime number.
No, a prime number is only divisible by itself and one. And since one doesn't count as a prime number, no.
No, ten is not a prime number since it can be divided by two. A prime number can only be divided by itself and one.
241 is a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since there are no factors of 241 other than one and itself it is a prime number.
Prime. It is only divisible by itself and one.
3 is a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since there are no factors of 3 other than one and itself it is a prime number.
Because one does not go into zero. A prime number is any number that has only one and itself as factors. Since one goes in to zero no times, the number is not prime.
2 is a prime number because its only factors are one and itself. Since 2 is a prime number, if it is a factor of your number, it is a prime factor.
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.
413 is not a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since 7 and 59 are factors of 413 that makes it a composite number (not prime).
415 is not a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since 5 and 83 are factors of 415 that makes it a composite number (not prime).
3193 is not a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since 31 and 103 are factors of 3193 that makes it a composite number (not prime).
