The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 154 are 2 x 7 x 11

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 921 are 3 x 307

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

Given numbers are 843, 154, 486, 921

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

Apply this formula for all numbers.

Step1:

LCM(843, 154) = 129822

GCD(843, 154) = ( 843 x 154 ) / 129822

= 843 / 154

= 843

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 843, 154, 486, 921 is 1
