Given numbers are 643, 939, 681, 841

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

Apply this formula for all numbers.

Step1:

LCM(643, 939) = 603777

GCD(643, 939) = ( 643 x 939 ) / 603777

= 643 / 939

= 643

Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

Step3:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

So, Greatest Common Divisor of 643, 939, 681, 841 is 1
