Given numbers are 243, 465, 189, 568

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

Apply this formula for all numbers.

Step1:

LCM(243, 465) = 37665

GCD(243, 465) = ( 243 x 465 ) / 37665

= 243 / 465

= 243

Step2:

LCM(3, 189) = 189

GCD(3, 189) = ( 3 x 189 ) / 189

= 3 / 189

= 3

Step3:

LCM(3, 568) = 1704

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

= 3 / 568

= 3

So, Greatest Common Divisor of 243, 465, 189, 568 is 1
