The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 685 are 5 x 137

Prime factors of 843 are 3 x 281

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

Given numbers are 921, 975, 685, 843

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

Apply this formula for all numbers.

Step1:

LCM(921, 975) = 299325

GCD(921, 975) = ( 921 x 975 ) / 299325

= 921 / 975

= 921

Step2:

LCM(3, 685) = 2055

GCD(3, 685) = ( 3 x 685 ) / 2055

= 3 / 685

= 3

Step3:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

So, Greatest Common Divisor of 921, 975, 685, 843 is 1
