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)
Instead of just giving you the answer, I will do steps. First: Let "x" be the number Therefore, 2x = 78. x = 78/2 x = 39 The number is 39
2 x 3 x 13 = 78 No exponents are needed.
2 x 3 x 13 is the answer. 78 is easily divisible by 2 so that makes 2 and 39. Then 39 becomes 3 and 13.
1 x 78 2 x 39 are two ways.
It is: 2*3*13 = 78
x 78, 2 x 39, 3 x 26, 6 x 13, 13 x 6, 26 x 3, 39 x 2, 78 x 1 = 78
6 x 13 3 x 26 2 x 39 1 x 78
1 x 78, 2 x 39, 3 x 26, 6 x 13.
39 x 2 = 78
1 x 78, 2 x 39, 3 x 26, 6 x 13 = 78
2 x 3 x 13 = 78 2 x 3 x 13
1 x 78, 2 x 39, 3 x 26, 6 x 13 = 78
78 = 2 x 3 x 13
2 x 3 x 13 = 78
2 x 3 x 13 = 78
2 x 3 x 13 = 78
