The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 188 are 2 x 2 x 47

Prime factors of 398 are 2 x 199

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

Given numbers are 545, 260, 188, 398

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

Apply this formula for all numbers.

Step1:

LCM(545, 260) = 28340

GCD(545, 260) = ( 545 x 260 ) / 28340

= 545 / 260

= 545

Step2:

LCM(5, 188) = 940

GCD(5, 188) = ( 5 x 188 ) / 940

= 5 / 188

= 5

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 545, 260, 188, 398 is 1
