Given numbers are 609, 570, 495, 657

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

Apply this formula for all numbers.

Step1:

LCM(609, 570) = 115710

GCD(609, 570) = ( 609 x 570 ) / 115710

= 609 / 570

= 609

Step2:

LCM(3, 495) = 495

GCD(3, 495) = ( 3 x 495 ) / 495

= 3 / 495

= 3

Step3:

LCM(3, 657) = 657

GCD(3, 657) = ( 3 x 657 ) / 657

= 3 / 657

= 3

So, Greatest Common Divisor of 609, 570, 495, 657 is 3
