A factor tree isn't complete until all the factors are prime. If any of the factors are composite, you know the factor tree is not complete.

no it does not matter what two factors you select to complete a factor tree (i just learned that today in class :D)

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.

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.

When the bottom branch is all prime numbers.

you use a factor tree

Probably 5, since it is the largest prime factor.

873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.

A factor tree is a way to notate the process of finding the prime factorization of a given number by writing the number at the top and breaking it down into factors on subsequent lines or "branches." The tree is complete when the bottom branch consists only of prime numbers.

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.

A Factor tree is when you put your number there and then find what makes that answer, you know it is done when you have all prime numbers. ~6th grader @ Celia Hays Elementary

It doesn't matter what factors you select to start a factor tree. The only thing that matters about completing it is that all the factors are prime.

Not particularly, as long as they are prime.

When the bottom row consists of all 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.

When you can no longer break down factors. when all the numbers at the bottom are prime!

When the bottom branch consists entirely of prime numbers.

125 5 x 25 5 x (5x5) Since 5 is a prime number, the factor tree is complete.

It's not where you start, it's where you finish. It doesn't matter what factors you select to start a factor tree, as long as all the factors are prime when you finish.

9 x 4 will not complete a factor tree, but both 9 x 4 and 12 x 3 will get to 2 x 2 x 3 x 3 which will.

factor tree of 216

Factor tree of 204

The factor tree is awsome!

The factor tree for the number 956 would be written out as 2*2*239. To find the factor tree you can use a factor tree calculator to get the answer you need.
