1997 is already prime; no tree.
350=2x5x5x7
194 2 x 97 Since both 2 and 97 are prime numbers, the prime factorization tree is complete.
there is NO factor tree (prime factorization) of 29.
240
1997 is already prime; no tree.
51 3,17
350=2x5x5x7
a prime factorization tree
33 11,3
That is correct, the prime factorization of 240 is 24 x 3 x 5
240 = 24 x 31 x 51
The prime factorization of 97 is 97 itself, as it is a prime number and cannot be divided evenly by any other numbers. Therefore, there is no prime factorization tree for the number 97.
