GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 618) = 100734
GCD(489, 618) = ( 489 x 618 ) / 100734
= 489 / 618
= 489
Step2:
LCM(3, 573) = 573
GCD(3, 573) = ( 3 x 573 ) / 573
= 3 / 573
= 3
Step3:
LCM(3, 494) = 1482
GCD(3, 494) = ( 3 x 494 ) / 1482
= 3 / 494
= 3
So, Greatest Common Divisor of 489, 618, 573, 494 is 1
