Given numbers are 618, 664, 209, 189

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

Apply this formula for all numbers.

Step1:

LCM(618, 664) = 205176

GCD(618, 664) = ( 618 x 664 ) / 205176

= 618 / 664

= 618

Step2:

LCM(2, 209) = 418

GCD(2, 209) = ( 2 x 209 ) / 418

= 2 / 209

= 2

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 618, 664, 209, 189 is 1
