The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 759 are 3 x 11 x 23

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 755 are 5 x 151

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

Given numbers are 921, 759, 243, 755

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

Apply this formula for all numbers.

Step1:

LCM(921, 759) = 233013

GCD(921, 759) = ( 921 x 759 ) / 233013

= 921 / 759

= 921

Step2:

LCM(3, 243) = 243

GCD(3, 243) = ( 3 x 243 ) / 243

= 3 / 243

= 3

Step3:

LCM(3, 755) = 2265

GCD(3, 755) = ( 3 x 755 ) / 2265

= 3 / 755

= 3

So, Greatest Common Divisor of 921, 759, 243, 755 is 1
