2 x 3 x 5 x 5 = 150, the GCF.
The GCF is 75.
It doesn't matter what method you use, you still need at least two numbers to find something in common.
Trees aren't necessary. Since 36 is a factor of 144, it is automatically the GCF. But if you insist... 144 72,2 36,2,2 18,2,2,2 9,2,2,2,2 3,3,2,2,2,2 36 18,2 9,2,2 3,3,2,2

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.Since 118 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 118 is 118
Example: 30 and 42The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
Trees aren't necessary. The greatest common multiple of any set of numbers is always infinite.
51 3,17 81 9,9 3,3,9 3,3,3,3 The GCF is 3.
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.
You need at least two factor trees to find a GCF.

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

All I did was make a factor tree. The GCF (Greatest Common Factor) is 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.
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.
Since 25 is a factor of 75, it is automatically the GCF, but if you insist... 25 5,5 75 25,3 5,5,3 Select the common factors. 5 x 5 = 25, the GCF
It doesn't matter what method you use, you still need at least two numbers to find something in common.
