Given numbers are 841, 403, 777, 643

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

Apply this formula for all numbers.

Step1:

LCM(841, 403) = 338923

GCD(841, 403) = ( 841 x 403 ) / 338923

= 841 / 403

= 841

Step2:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 841, 403, 777, 643 is 1
