29x3 both prime so your done
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
Prime numbers don't have factor trees. So if you can create a tree, your number's composite.
A factor tree is a representation of the process of finding the prime factorization of a given number.
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
87 3,29
87 3,29 Not much of a tree. More like a factor shrub.
873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.
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.

29x3 both prime so your done
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.
29 is already prime. No tree. 87 3,29 Since there are no common prime factors, the GCF is 1.
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
There is no factor tree nor factors of 57 as it is a prime number.
13 is a prime number so it doesn't have a factor tree.
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 58 and 87, you can list the factors of each number and identify the largest number they have in common. The factors of 58 are 1, 2, 29, and 58, while the factors of 87 are 1, 3, 29, and 87. The greatest common factor of 58 and 87 is 29.
