The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 818 are 2 x 409

Prime factors of 985 are 5 x 197

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 978, 818, 985, 843

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

Apply this formula for all numbers.

Step1:

LCM(978, 818) = 400002

GCD(978, 818) = ( 978 x 818 ) / 400002

= 978 / 818

= 978

Step2:

LCM(2, 985) = 1970

GCD(2, 985) = ( 2 x 985 ) / 1970

= 2 / 985

= 2

Step3:

LCM(1, 843) = 843

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

= 1 / 843

= 1

So, Greatest Common Divisor of 978, 818, 985, 843 is 1
