It is 9 derived as:
Prime Factors of 36: 2x2x3x3
Prime Factors of 45: 5x3x3
Prime Factors of 54: 2x3x3x3
The common prime factors of all the three numbers are 3x3 = 9
To check you answer:
1. Divide all the three numbers by 9 and they shall be perfectly divisible
2. Try and divide non common factors of each number by other two, it would not be perfectly divisible (i.e. Try and divide 54 by 5)
