Given numbers are 680, 749, 177, 255

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 749 are 7 x 107

Prime factors of 177 are 3 x 59

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 680, 749, 177, 255

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

Apply this formula for all numbers.

Step1:

LCM(680, 749) = 509320

GCD(680, 749) = ( 680 x 749 ) / 509320

= 680 / 749

= 680

Step2:

LCM(1, 177) = 177

GCD(1, 177) = ( 1 x 177 ) / 177

= 1 / 177

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 680, 749, 177, 255 is 1
