Given numbers are 680, 845, 180, 428

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 845 are 5 x 13 x 13

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 680, 845, 180, 428

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

Apply this formula for all numbers.

Step1:

LCM(680, 845) = 114920

GCD(680, 845) = ( 680 x 845 ) / 114920

= 680 / 845

= 680

Step2:

LCM(5, 180) = 180

GCD(5, 180) = ( 5 x 180 ) / 180

= 5 / 180

= 5

Step3:

LCM(5, 428) = 2140

GCD(5, 428) = ( 5 x 428 ) / 2140

= 5 / 428

= 5

So, Greatest Common Divisor of 680, 845, 180, 428 is 1
