Given numbers are 813, 939, 545, 981

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

Apply this formula for all numbers.

Step1:

LCM(813, 939) = 254469

GCD(813, 939) = ( 813 x 939 ) / 254469

= 813 / 939

= 813

Step2:

LCM(3, 545) = 1635

GCD(3, 545) = ( 3 x 545 ) / 1635

= 3 / 545

= 3

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 813, 939, 545, 981 is 1
