A factor tree is a visual metod of breaking down any number into its consituent set of Prime number factors. in the case of 66: 66 = 33 x 2 = 11 x 3 x 2 where 11, 3 and 2 are prime numbers and cannot be split down further. Each slit can be represented visually as a branch with the composite numbers at rhe end of each twig giving the name as a factor 'tree'.
66 33,2 11,3,2
The greatest common factor 54 and 66 is 23.
132-2 | 66-2 | 33-3 | 11
3 is the smallest number that is a factor 66 and a multiple of 3
factor tree of 216
61 is already prime. It doesn't need a tree.
66 33,2 11,3,2
66 33,2 11,3,2
66 33,2 11,3,2
66 33,2 11,3,2
66 33,2 11,3,2
66 33*22 11*6
66 33,2 11,3,2 2 x 3 x 11 = 66
the answer i think is 2,3 or 2 and 11 hope i helped :).
A commonly used factor tree for 132 is: 132 11 12 11 4 3 11 2 4 3 Another factor tree for 132 is: 132 66 2 22 3 2 11 2 3 2 Yet another factor tree for 132 is: 132 66 2 33 2 2 11 3 2 2 Hey for the first factor tree 4 isn't prime
Six is a factor of 66.
662, 332, 3, 11or666, 112, 3, 11or663, 223, 2, 11
