No,you are wrong.It is 18
36=2*2*3*3
54=2*3*3*3
180=2*2*3*3*5
Therefore GCF
=2*3*3
=18

36 = 4 x 9 = 2^2 X (3^2)
54 = 6 x 9 = 2 x (3^3)
180 = 4 x 45 = 2^2 x 3^2 X 5
HCF (36, 54,180) = 2 X 3^2 = 18

No one can do math anymore...
The answer is not 2, 6 or 12....
The correct answer is 18
2 & 6 are too small
12 does not go into 54 evenly
2 x 18 = 36
3 x 18 = 54
10 x 18 = 180

No. Consider the canonical forms:
36 = (2^2)*(3^2)*(5^0)
54 = (2^1)*(3^3)*(5^0)
180 = (2^2)*(3^2)*(5^1) .
The g. c. f. is the product of each prime raised to its minimum exponent in the above array. Thus, g. c. f. = (2^1)*(3^2)*(5^0)
or 2*9 = 18.

36 = 3*3*2*2 = [3*3*2]*2
54 = 3*3*2*3 = [3*3*2]*3
180 = 3*3*2*2*5 = [3*3*2]*2*5
In all these [3*3*2] is common
greatest common factor of 36, 54, 108 = [3*3*2] = 18

GCF of 36,54 and180=18.ANS
You are wrong.Not correct.

Well, they are all divisible by 18.
18x3=36
18x4=54
18x10=180
So the GCF is 18.

no, it's twelve. The greatest means the biggest.
whoops, looks like it's eighteen form the other posts. But the point is the same, greatest means biggest or largest number.
