Given numbers are 626, 305, 570, 390

The list of prime factors of all numbers are

Prime factors of 626 are 2 x 313

Prime factors of 305 are 5 x 61

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 626, 305, 570, 390

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

Apply this formula for all numbers.

Step1:

LCM(626, 305) = 190930

GCD(626, 305) = ( 626 x 305 ) / 190930

= 626 / 305

= 626

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 626, 305, 570, 390 is 1
