Given numbers are 420, 195, 439, 255

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 195 are 3 x 5 x 13

Prime factors of 439 are 439

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 420, 195, 439, 255

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

Apply this formula for all numbers.

Step1:

LCM(420, 195) = 5460

GCD(420, 195) = ( 420 x 195 ) / 5460

= 420 / 195

= 420

Step2:

LCM(15, 439) = 6585

GCD(15, 439) = ( 15 x 439 ) / 6585

= 15 / 439

= 15

Step3:

LCM(1, 255) = 255

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

= 1 / 255

= 1

So, Greatest Common Divisor of 420, 195, 439, 255 is 1
