Given numbers are 317, 455, 372, 680

The list of prime factors of all numbers are

Prime factors of 317 are 317

Prime factors of 455 are 5 x 7 x 13

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 317, 455, 372, 680

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

Apply this formula for all numbers.

Step1:

LCM(317, 455) = 144235

GCD(317, 455) = ( 317 x 455 ) / 144235

= 317 / 455

= 317

Step2:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 317, 455, 372, 680 is 1
