Given numbers are 669, 420, 621, 543

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

Apply this formula for all numbers.

Step1:

LCM(669, 420) = 93660

GCD(669, 420) = ( 669 x 420 ) / 93660

= 669 / 420

= 669

Step2:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

Step3:

LCM(3, 543) = 543

GCD(3, 543) = ( 3 x 543 ) / 543

= 3 / 543

= 3

So, Greatest Common Divisor of 669, 420, 621, 543 is 3
