First, find the factors:
36 = 2*2*3*3
60 = 2*2*3*5
135 = 3*3*3*5
3 is the only common factor, so the gcf=3
LCM(36, 60, 135) = 540 GCF(36, 60, 135) = 3
The GCF is 3.

k
If that's 36, 60 and 135, the GCF is 3. If that's 3660 and 135, the GCF is 15.
The GCF is 3.
The GCF is: 3
The GCF is 9.
The GCF is: 9
GCF of 36 and 60 is 12.
The GCF of 60 and 135 is 15.
The GCF is 6.
