Given numbers are 261, 549, 170, 528

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 549 are 3 x 3 x 61

Prime factors of 170 are 2 x 5 x 17

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 261, 549, 170, 528

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(261, 549) = 15921

GCD(261, 549) = ( 261 x 549 ) / 15921

= 261 / 549

= 261

Step2:

LCM(9, 170) = 1530

GCD(9, 170) = ( 9 x 170 ) / 1530

= 9 / 170

= 9

Step3:

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

= 1 / 528

= 1

So, Greatest Common Divisor of 261, 549, 170, 528 is 1
