Given numbers are 395, 208, 427, 720

The list of prime factors of all numbers are

Prime factors of 395 are 5 x 79

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 427 are 7 x 61

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 395, 208, 427, 720

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

Apply this formula for all numbers.

Step1:

LCM(395, 208) = 82160

GCD(395, 208) = ( 395 x 208 ) / 82160

= 395 / 208

= 395

Step2:

LCM(1, 427) = 427

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

= 1 / 427

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 395, 208, 427, 720 is 1
