18 6 x 3 (2x3) x 3 Since 2 and 3 are prime numbers, the factor tree is complete. An alternate version of the factor tree for 18 is: 18 2 x 9 2 x (3x3)
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)
The prime factorization.
78 6 x 13 (2x3) x 13 The numbers 2, 3, and 13 are prime numbers, so the factor tree is complete. An alternate version of a factor tree for 78 is: 78 2 x 39 2 x (3x13)
