GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 264) = 27192
GCD(618, 264) = ( 618 x 264 ) / 27192
= 618 / 264
= 618
Step2:
LCM(6, 393) = 786
GCD(6, 393) = ( 6 x 393 ) / 786
= 6 / 393
= 6
Step3:
LCM(3, 643) = 1929
GCD(3, 643) = ( 3 x 643 ) / 1929
= 3 / 643
= 3
So, Greatest Common Divisor of 618, 264, 393, 643 is 1
