256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2
Basically, just divide the number by prime numbers until you reach 1
256 / 2 = 128
128/ 2 = 64
64 / 2 = 32
32 / 2 = 16
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2
2 / 2 = 1
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
With a factor tree, yes.

Their at the bottom of the tree because the hole point of a factor tree is to find the prime factorization of the number, so it would be at the bottom of the tree.
Use a factor tree. 186 93,2 31,3,2
