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 the greatest prime factor of 96?
Use a factor tree. 96 48,2 24,2,2 12,2,2,2 6,2,2,2,2 3,2,2,2,2,2 The greatest prime factor of 96 is 3.
How do you find the GCF of 13 and 26?
Method 1:Find the factors of both numbers.13: 1;1326: 1;2;13;26The greatest number after the ":" (called a colon) that both numbers have in common is the GCF, or Greatest Common FactorMethod 2:Use a factor tree (better for integers and larger numbers) to find prime factorization13^1, 13
What is a factor tree look like?
A factor tree is when you take a number and bring it down to prime numbers. You do this by diving the number, and drawing to lines from the number and putting the two numbers that multiply into the starting number. You do that until you have all prime numbers. This skill can be usefull for greatest common factor and lowest commen multiple.
Why are prime numbers at the bottom of the factor tree?
Their at the bottom of the tree because the hole point of a factor tree is to find the prime factorization of the number, so it would be at the bottom of the tree.
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.
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 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
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.
