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.

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.


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 GCF of 40 and 35?

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


How do you use the factor tree to find the greatest common factor of 16 and 24?

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.
