19 is already prime. No need for a tree.19 is prime. No tree.
133 7 x 19 Both 7 and 19 are prime numbers, so the factor tree is complete.
323 17 x 19 Both 17 and 19 are prime numbers, so the factor tree is finished.
11*19
Do a factor tree. 15 ^ 5 3 (3 & 5 are prime) 19 is a prime number. 15: 3 * 5 19: 19 ^^They have nothing in common. Therefore, the answer is 1.
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
The purpose of a factor tree is to notate the process of finding the prime factorization. If a number is already prime, a factor tree is not necessary.
5 x 19
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
