Given numbers are 388, 455, 770, 318

The list of prime factors of all numbers are

Prime factors of 388 are 2 x 2 x 97

Prime factors of 455 are 5 x 7 x 13

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 318 are 2 x 3 x 53

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

Given numbers are 388, 455, 770, 318

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

Apply this formula for all numbers.

Step1:

LCM(388, 455) = 176540

GCD(388, 455) = ( 388 x 455 ) / 176540

= 388 / 455

= 388

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

= 1 / 318

= 1

So, Greatest Common Divisor of 388, 455, 770, 318 is 1
