323 17 x 19 Both 17 and 19 are prime numbers, so the factor tree is finished.
133 7 x 19 Both 7 and 19 are prime numbers, so the factor tree is complete.
11*19
285 15 x 19 (3 x 5) x 19 The factor tree has reduced 285 to its prime factors: 3, 5, and 19.
I can't draw a factor tree here 76 / 2 = 38 38 / 2 = 19 Prime factorization is 2, 2, 19
5 x 19
57/3 = 19 19*3=57
57 3, 19 Note: 19 is a prime number
76= 2•2•19
6859 / \ 19 361 / \ 19 19 6859= 19 x 19 x 19 (19 to the power of 3).
