The list of prime factors of all numbers are

Prime factors of 543 are 3 x 181

Prime factors of 357 are 3 x 7 x 17

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 543, 357, 920, 770

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

Apply this formula for all numbers.

Step1:

LCM(543, 357) = 64617

GCD(543, 357) = ( 543 x 357 ) / 64617

= 543 / 357

= 543

Step2:

LCM(3, 920) = 2760

GCD(3, 920) = ( 3 x 920 ) / 2760

= 3 / 920

= 3

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 543, 357, 920, 770 is 1
