Given numbers are 813, 136, 573, 861

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

Apply this formula for all numbers.

Step1:

LCM(813, 136) = 110568

GCD(813, 136) = ( 813 x 136 ) / 110568

= 813 / 136

= 813

Step2:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 813, 136, 573, 861 is 1
