Given numbers are 680, 197, 521, 485

The list of prime factors of all numbers are

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

Prime factors of 197 are 197

Prime factors of 521 are 521

Prime factors of 485 are 5 x 97

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

Given numbers are 680, 197, 521, 485

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

Apply this formula for all numbers.

Step1:

LCM(680, 197) = 133960

GCD(680, 197) = ( 680 x 197 ) / 133960

= 680 / 197

= 680

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 680, 197, 521, 485 is 1
