The factor tree would be hard to show so here is the prime factorization.41 times 5
8
there is NO factor tree (prime factorization) of 29.
Use a factor tree. 1023 341,3 31,11,3
Use a factor tree. 78 39,2 13,3,2
the prime factorization of 32 is 2x2x2x2x2 and the factor tree is 32 8 4 2x4 2x2 2x2
352 prime factorization tree
Use a factor tree. 36 18,2 9,2,2 3,3,2,2
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
