Given numbers are 813, 558, 570, 486

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, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

= 3 / 570

= 3

Step3:

LCM(3, 486) = 486

GCD(3, 486) = ( 3 x 486 ) / 486

= 3 / 486

= 3

So, Greatest Common Divisor of 813, 558, 570, 486 is 3
