The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 652 are 2 x 2 x 163

Prime factors of 255 are 3 x 5 x 17

Prime factors of 427 are 7 x 61

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

Given numbers are 391, 652, 255, 427

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

Apply this formula for all numbers.

Step1:

LCM(391, 652) = 254932

GCD(391, 652) = ( 391 x 652 ) / 254932

= 391 / 652

= 391

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 391, 652, 255, 427 is 1
