Given numbers are 813, 558, 864, 939

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

Apply this formula for all numbers.

Step1:

LCM(813, 558) = 151218

GCD(813, 558) = ( 813 x 558 ) / 151218

= 813 / 558

= 813

Step2:

LCM(3, 864) = 864

GCD(3, 864) = ( 3 x 864 ) / 864

= 3 / 864

= 3

Step3:

LCM(3, 939) = 939

GCD(3, 939) = ( 3 x 939 ) / 939

= 3 / 939

= 3

So, Greatest Common Divisor of 813, 558, 864, 939 is 3
