Given numbers are 680, 190, 639, 544

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 190 are 2 x 5 x 19

Prime factors of 639 are 3 x 3 x 71

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Given numbers are 680, 190, 639, 544

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

Apply this formula for all numbers.

Step1:

LCM(680, 190) = 12920

GCD(680, 190) = ( 680 x 190 ) / 12920

= 680 / 190

= 680

Step2:

LCM(10, 639) = 6390

GCD(10, 639) = ( 10 x 639 ) / 6390

= 10 / 639

= 10

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 680, 190, 639, 544 is 1
