Shorter factor strings aren't composed entirely of prime numbers.
It varies with each given number.
It is a square of that factor. E.g. 5 is a distinct factor of 25. If you multiply that distinct factor by itself (5*5) you get 25. A square comes from the x^2 notation and is any number which has a factor which is multiplied by itself.
The longest factor string of any composite number is its prime factorization.
5 x 5
The longest factor string is 2x2x2x3x13. It is always best to list your factor string from the least to greatest number.
For composite numbers, only one string of factors is the longest; the prime factorization.
No, 12 is not a prime number.
A perfect square
10 of them.
The prime factorization
The length of a factor string of a given number is limited by how many factors there are. The smallest are factor pairs, the longest is the prime factorization.2 x 18 = 362 x 2 x 9 = 362 x 2 x 3 x 3 = 36Factor strings are the 2 numbers that equal to the number that has been asked to you
