How do you use a factor tree to find the greatest common factor of 87 and 29?

It's not necessary for two reasons. First, 29 is a factor of 87 so it will automatically be the GCF of this problem. Second, since factor trees are designed to find prime numbers and 29 is already prime, it doesn't have a tree. But if you insist...
87
3,29
Here we have a factor tree, more like a factor shrub, that shows that the prime factors of 87 are 3 and 29. Since 29 is a factor of 29, the GCF is 29.

How do you use a factor tree to find the greatest common factor of 78 and 195?
Find out about factors and factor trees.
What is the greatest common factor of a factor tree?
You need at least two factor trees to find a GCF.
How can you find a greatest common multiple by using a factor tree?
Trees aren't necessary. The greatest common multiple of any set of numbers is always infinite.
How do you use a factor tree to find the greatest common factor of 88?
A factor tree will show you the prime factorization of 88. Comparing that prime factorization of 88 and another number will you show you the GCF between the two. You need at least two numbers to find a GCF.
How do you use the factor tree to find the greatest common factor of 8 and 18?
8 4,2 2,2,2 18 9,2 3,3,2 The GCF is 2.
How do you use a factor tree to find the greatest common factor of 24 and 90?
244 62 2 2 3909 103 3 2 5The only factors common to 24 and 90 are 2 and 3, so the greatest common factor is their product, 6.
How do do a factor tree to find the greatest common factor of 18 and 15?
153,5189,23,3,23 x 5 = 152 x 3 x 3 = 18Select the common factor.The GCF is 3.
How do you draw the factor tree for the greatest common factor of 1350?
2,675 2,5,125 2,5,5,25 2,5,5,5,5
What is the greatest common factor of 48 using the factor tree?
The factors of 48 are 1,2,3,4,6,8,12,16,24 and 48. You need another set of factors to compare them with to find a GCF.
What is the GCF of 40 and 35?
All I did was make a factor tree. The GCF (Greatest Common Factor) is 5. :)
How do you find least common multiple and greatest common factor by using the factor tree?
greatest common factor the tree way:ex:25&30 25 30 ^ ^ 5x5 5x6 5x5 are prime numbers so leave it. 5x ^ 5x2x3 2x3=6 then line them up like this:25:5x5 30:5x2x3 then make sum matches.5 and 5 are the only matches so the greatest common factors are 5
What is the greatest common factor tree?
That doesn't really exist. A factor tree is a way to notate the process of finding the prime factorization of a given number. The greatest common factor, or GCF, is the largest number that can divide evenly with no remainder into a given set of numbers.
