The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 417 are 3 x 139

Prime factors of 309 are 3 x 103

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

Given numbers are 851, 988, 417, 309

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

Apply this formula for all numbers.

Step1:

LCM(851, 988) = 840788

GCD(851, 988) = ( 851 x 988 ) / 840788

= 851 / 988

= 851

Step2:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 851, 988, 417, 309 is 1
