No you cannot. You might want to try the factor tree for 27.
It depends what you mean by symmetric. If you mean that there are the same number of factors on each branch, then the answer is No. eg 20 / \ 4 5 / \ 2 2
Yes.
1 is the smallest natural number. 1 is the factor of every number. 1 is neither prime nor composite.
No
No, 1 is a factor of every whole number because 1 is a factor of every whole number.

Yes.
No. As soon as you have more than two, it's composite.
All even numbers are composite, because 2 is a factor of every even number.
1 is neither a prime number nor a composite number. Its only factor is itself whereas every prime number has two factors: 1 and itself.
1 is a factor of every number.1 is a factor of every number.
yes every even number is composite
no, because a composite number can be found by multiplying three prime numbers. 3*2*5 = 30, and 30 is a composite number and also has 3 prime factors. Every prime number has 1 prime factor by the way, itself. 1 is neither prime nor composite.
That is how they are defined. Any number greater than 1 is composite if it has a factor other than 1 and itself. If it is not a composite number then it is a prime number. It mustbe one or the other and the result follows.
1 is the smallest natural number. 1 is the factor of every number. 1 is neither prime nor composite.
Every number has at least one factor, the number 1.Every number greater than 1 has at least two factors, 1 and itself.Any number with exactly 2 factors is prime.Any number with more than 2 factors is composite; in this case it can be factorised completely into primes.The number 1 has only one factor. It is therefore neither prime nor composite.
No.
