GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 579) = 55005
GCD(285, 579) = ( 285 x 579 ) / 55005
= 285 / 579
= 285
Step2:
LCM(3, 168) = 168
GCD(3, 168) = ( 3 x 168 ) / 168
= 3 / 168
= 3
Step3:
LCM(3, 558) = 558
GCD(3, 558) = ( 3 x 558 ) / 558
= 3 / 558
= 3
So, Greatest Common Divisor of 285, 579, 168, 558 is 3
