34 /\ 2 17
factor tree of 68:(68) = 2 * (34)(34) = 2 * 17so prime factors are 2 * 2 * 17
34 2,17
2x2x2x2x3x3x3x3 or 24 x 34
As there is no common factor between 7 and 34 other than 1, 7/34 is already in simplest form.
2 x 17 = 34
68 /\ 2 34 /\ 2 17
612 18 x 34 6x3 17x2 2x3x3 17x2
102 6 x 17 (2x3) x 17 The numbers 2, 3, and 17 are prime numbers, so the factor tree is complete. An alternate version of a factor tree of 102 is: 102 3 x 34 3 x (2x17)
8 is not a factor of 34.
