Given numbers are 839, 861, 643, 127

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

Apply this formula for all numbers.

Step1:

LCM(839, 861) = 722379

GCD(839, 861) = ( 839 x 861 ) / 722379

= 839 / 861

= 839

Step2:

LCM(1, 643) = 643

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

= 1 / 643

= 1

Step3:

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

= 1 / 127

= 1

So, Greatest Common Divisor of 839, 861, 643, 127 is 1
