question:make a factor tree for 36. 6 to the fifth power 6to the fifther power time 6
61 is already prime. It doesn't need a tree.
Just put 6 at the top of your tree and then have 2 and 3 coming off of it.
A factor tree of 78: 78 6 x 13 (2x3) x 13 Since 2, 3, and 13 are prime numbers, the factor tree is complete.
426,72,3,7
78 6 x 13 (2x3) x 13 Since 2, 3, and 13 are prime numbers, the factor tree is complete.
12*6 4*3*2*3
Make a factor-tree and the look for the matches of their prime factorization... Using 6 and 8: 6......... 8 2x3.....4x2 .........2x2 so the prime factorization of 6 is 2x3 and 8 is 2x2x2 so the only match you have is two so the gcf of 6 and 8 is 2
72 / \ 2 36 / \ 6 6 / \ / \ 3 2 3 2
IT IS PRIME there is no factor tree
