Best Answer

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.

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

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.

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

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

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.

164 42 2 2 2244 62 2 2 3The only common factors of 16 and 24 are 2, 2, and 2, so their greatest common factor is the product of 2 x 2 x 2, 8.
