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

Given numbers are 681, 187, 800, 643

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

Apply this formula for all numbers.

Step1:

LCM(681, 187) = 127347

GCD(681, 187) = ( 681 x 187 ) / 127347

= 681 / 187

= 681

Step2:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 681, 187, 800, 643 is 1
