The list of prime factors of all numbers are

Prime factors of 626 are 2 x 313

Prime factors of 345 are 3 x 5 x 23

Prime factors of 309 are 3 x 103

Prime factors of 258 are 2 x 3 x 43

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

Given numbers are 626, 345, 309, 258

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

Apply this formula for all numbers.

Step1:

LCM(626, 345) = 215970

GCD(626, 345) = ( 626 x 345 ) / 215970

= 626 / 345

= 626

Step2:

LCM(1, 309) = 309

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

= 1 / 309

= 1

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 626, 345, 309, 258 is 1
