If I may use an English analogy, factors are like letters and factor strings are like sentences. Factors are numbers that can be multiplied together to create products. Factor strings are factors multiplied together. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 Factor strings for 24 include 2 x 12, 3 x 8, 4 x 6, 2 x 2 x 6, 2 x 3 x 4 and 2 x 2 x 2 x 3
The longest factor string for 9 is 3 x 3.
The longest factor string of 44 is contained within the longest factor string of 132.
It can. Square numbers have repeated factors.
What are the factor strings of 120
Any multiple of 10.
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.
Shorter factor strings aren't composed entirely of prime numbers.
Factor strings are multiplication sentences. 3 x 3 is a factor string for 9.
41 is prime. No strings.
23 is prime. No strings.
There are short strings of digits which will repeat, but there is no sequence which will repeat forever.
37 is prime. Two factors. No strings.
Three.
One
