Given numbers are 680, 641, 260, 457

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 641 are 641

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 457 are 457

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

Given numbers are 680, 641, 260, 457

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

Apply this formula for all numbers.

Step1:

LCM(680, 641) = 435880

GCD(680, 641) = ( 680 x 641 ) / 435880

= 680 / 641

= 680

Step2:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 680, 641, 260, 457 is 1
