That is a very good question. The awnser is quite simple, its a number.
The number is 16.

The only name is factorization.
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.

the prime factorization
A factor free is a diagram showing the prime factorization of a number.
It is a factor of 32, which means it is one of 1, 2, 4, 8, 16, and 32. The perfect squares among the factors of 32 are 4 and 16. Of those two, the only one with a sum of digits that is odd is 16.
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
65
If the prime factorization contains a 5 and a 7, 35 is a factor.
