You can not find the greatest common factor for just one number. Ill will choose another number to compare 33 with. Lets choose 88.
First take 33 and find all the numbers it divides into by a whole number
33/3 = 11 So 3 and 11
33/33 = 1 So 1 and 33
the only factors are 3 and 11 ... 3x11=33
and 1 and 33 ... 1x33=33
it is written like this...
33 - 1,3,11,33
Now take 88 and find all the numbers that it divides into by a whole number
88/2 = 44 So 2 and 44
88/4 = 22 So 4 and 22
88/8 = 11 So 8 and 11
88/88 = 1 So 1 and 88
So the factors of 88 are ... 2x44=88 ; 4x22=88 ; 8x11=88 ; 1x88=88
it is written like this
88 - 1, 2, 4, 8, 11, 22, 44, 88
Now take all of the factors of 33 and 88 and find the number that is in common and that is the greatest. Did you find it...
the answer is 11

Do factor trees always work for determining the greatest common factors?
If you construct them correctly, factor trees always work to determine the prime factorization of a number. Once you compare the prime factorizations of two or more numbers, it is relatively easy to find the greatest common factor of them from there.
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
