The prime factorization.
When all the factors are prime.
the longest string of prime factor for 30 is 2 x 3 x 5
The longest factor string for 42 is when we break down 42 into its prime factors. 42 can be expressed as 2 x 3 x 7. This is the longest factor string because these are the prime numbers that, when multiplied together, result in 42.
Factors are integers that can be multiplied together to create a product. Such multiplication sentences are called strings. The length of the string is how many numbers are in it. 6 x 4 is a factor string for 24. 2 x 3 x 4 is a longer factor string for 24. 2 x 2 x 2 x 3 is the longest factor string for 24. The longest factor string is also known as the prime factorization.
The prime factorization.
2x3x5
When all of the factors are prime. The longest factor string is the prime factorization.
Because 1 isn't prime.
When all the factors are prime.
The longest string of prime factors for 30 is 2 x 3 x 5 because there isn't a prime factor string that's longer.
Find the prime factors first.
The longest factor string for 840 is its prime factorization because prime factors can't be broken down any further.
the longest string of prime factor for 30 is 2 x 3 x 5
All of the factors are prime.
For composite numbers, only one string of factors is the longest; the prime factorization.
When each one of them is a prime.
