2 x 2 x 2 x 2 x 2 x 5
160 = 2x2x2x2x2x5
the prime factorization
A factor free is a diagram showing the prime factorization of a number.
If the prime factorization contains a 5 and a 7, 35 is a factor.
Each composite number has its own unique prime factorization. The largest number in that factorization would be the largest prime factor. It will never be more than half of the original number.
23 is a prime number and its only prime factor is 23.
A factor tree is a representation of the process of finding the prime factorization of a given number. It's complete when the bottom branch consists entirely of prime numbers.
the prime factorization
19 is a prime number, so it has no prime factorization.
A factor free is a diagram showing the prime factorization of a number.
If the prime factorization contains a 5 and a 7, 35 is a factor.
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
Each composite number has its own unique prime factorization. The largest number in that factorization would be the largest prime factor. It will never be more than half of the original number.
11 is a prime number. Its only prime factor is 11.
23 is prime.
That's a factor string of 980; it is not the prime factorization. 4 and 49 aren't prime.
Prime Factorization of 22 is a prime number, so it does not have a prime factorization.
When the bottom branch consists entirely of prime numbers.
