Given numbers are 688, 594, 220, 195

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 594 are 2 x 3 x 3 x 3 x 11

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 195 are 3 x 5 x 13

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

Given numbers are 688, 594, 220, 195

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

Apply this formula for all numbers.

Step1:

LCM(688, 594) = 204336

GCD(688, 594) = ( 688 x 594 ) / 204336

= 688 / 594

= 688

Step2:

LCM(2, 220) = 220

GCD(2, 220) = ( 2 x 220 ) / 220

= 2 / 220

= 2

Step3:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

So, Greatest Common Divisor of 688, 594, 220, 195 is 1
