The longest factor string of any composite number is its prime factorization.
The prime factorization
The prime factorization is the longest factor sting.
The longest factor string is the prime factorization
When all of the factors are prime. The longest factor string is the prime factorization.
The prime factorization.
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.
The longest factor string is 2x2x2x3x13. It is always best to list your factor string from the least to greatest number.
The longest factor string for 840 is its prime factorization because prime factors can't be broken down any further.
Factor strings don't necessarily have to be composed entirely of prime numbers. But the longest factor string, the one that is entirely prime numbers, that's the prime factorization.
the longest factor string for 840 is: 2x2x2x3x5x7. I hoped that helped m! Have a good rest of your day!
