Given numbers are 189, 627, 645, 568

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

Apply this formula for all numbers.

Step1:

LCM(189, 627) = 39501

GCD(189, 627) = ( 189 x 627 ) / 39501

= 189 / 627

= 189

Step2:

LCM(3, 645) = 645

GCD(3, 645) = ( 3 x 645 ) / 645

= 3 / 645

= 3

Step3:

LCM(3, 568) = 1704

GCD(3, 568) = ( 3 x 568 ) / 1704

= 3 / 568

= 3

So, Greatest Common Divisor of 189, 627, 645, 568 is 1
