Factor Tree is an intuitive method to understand the factors of a number. It shows how all the factors are been derived from the number. It is a special diagram where you find the factors of a number, then the factors of those numbers, etc until you can’t factor anymore. The ends are all the prime factors of the original number.
Input : v = 48 Output : Root of below tree 48 /\ 2 24 /\ 2 12 /\ 2 6 /\ 2 3
The factor tree is created recursively. A binary tree is used.
- We start with a number and find the minimum divisor possible.
- Then, we divide the parent number by the minimum divisor.
- We store both the divisor and quotient as two children of the parent number.
- Both the children are sent into function recursively.
- If a divisor less than half the number is not found, two children are stored as NULL.
