Given numbers are 680, 873, 861, 578

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 873 are 3 x 3 x 97

Prime factors of 861 are 3 x 7 x 41

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 680, 873, 861, 578

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

Apply this formula for all numbers.

Step1:

LCM(680, 873) = 593640

GCD(680, 873) = ( 680 x 873 ) / 593640

= 680 / 873

= 680

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 680, 873, 861, 578 is 1
