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.

You need at least two factor trees to find a GCF.

You must start with two numbers in order to find the greatest common factor of a set of numbers. The number 25 alone has no greatest common factor as their is no other number in order to have a factor in common with anything.

Trees aren't necessary. The greatest common multiple of any set of numbers is always infinite.

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.

8

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.

29 is already prime. No tree. 87 3,29 Since there are no common prime factors, the GCF is 1.

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.

2,675 2,5,125 2,5,5,25 2,5,5,5,5

All I did was make a factor tree. The GCF (Greatest Common Factor) is 5. :)

It doesn't matter what method you use, you still need at least two numbers to find something in common.

235 5,47 273 3,91 3,7,13 No common prime factors. The GCF is 1.

50 25,2 5,5,2

225 15 15 3 5 3 5 The factors of 225 are 3, 3, 5, and 5. A common factor is one common to each of two or more numbers. There is not greatest common factor when only one number is given.

The Greatest Common Factor of 40 and 100 is 20. 5x2x2. Use a factor tree and learn math!!!!!!!!!!!!!!

1 only has one factor, it doesn't have a tree. You can save time and effort by remembering that 1 is the GCF of any pair of numbers that includes 1.

The least common factor of any two numbers is one. You don't need a factor tree to tell you that.

The factor tree finds the prime factorization of a given number. Combining the prime factorizations of two denominators correctly will give you their least common denominator.

Since the p and the q have nothing in common, the common factor will just be for the coefficients (number part of the terms). The prime factors (from a factor tree) of 12 are 2 x 2 x 3, and those of 30 are 2 x 3 x 5. The only ones they both have in common are 2 and 3, so we multiply these and get the greatest common factor of 6.

8 4,2 2,2,2 18 9,2 3,3,2 The GCF is 2.

2 is a prime number, it doesn't have a factor tree. You can save time and effort by remembering that if the smaller of a pair of numbers is a factor of the larger one, it is automatically the GCF. The GCF of 2 and 36 is 2.

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

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.

LCM- using 14 12 and 10 is 420
