24x25
The number of numbers in the string; how long it is.
Factors of 20 are: 1 2 4 5 10 and 20
No.
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.
You need at least two numbers to find a GCF.

When a factor divides into a number, the result is a whole number. That's how you know the first number is a factor. If you were to allow the result to be a decimal, then all numbers would be factors. It defeats the purpose. Prime factorizations refer to whole numbers, not decimals.
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.
The factor tree finds the prime factorization of a given number. Combining the prime factorizations of two denominators correctly will give you their least common denominator.
