When the bottom branch consists entirely of prime numbers.
83 is prime. No tree.
61 is already prime. It doesn't need a tree.
145 5,29 Not much of a tree. More like a factor shrub.
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
the factor tree of 100100^50,2^25,2,2^5,5,2,21111
no it does not matter what two factors you select to complete a factor tree (i just learned that today in class :D)
873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.
A factor tree is a representation of the process of finding the prime factorization of a given number. It's complete when the bottom branch consists entirely of prime numbers.
A factor tree of 78: 78 6 x 13 (2x3) x 13 Since 2, 3, and 13 are prime numbers, the factor tree is complete.
133 7 x 19 Both 7 and 19 are prime numbers, so the factor tree is complete.
253 11 x 23 Both 11 and 23 are prime numbers, so the factor tree is complete.
Yes. Factors that complete a factor tree need to be prime. However, it doesn't matter what two factors you select to start a factor tree.
you use a factor tree
When the bottom branch is all prime numbers.
125 5 x 25 5 x (5x5) Since 5 is a prime number, the factor tree is complete.
62525 x 25(5x5) x (5x5)Since 5 is a prime number, the factor tree is complete.625125,525,5,55,5,5,5
242 2 x 121 2 x (11x11) Since 2 and 11 are prime numbers, the factor tree is complete.
