Given numbers are 639, 618, 717, 576

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

Apply this formula for all numbers.

Step1:

LCM(639, 618) = 131634

GCD(639, 618) = ( 639 x 618 ) / 131634

= 639 / 618

= 639

Step2:

LCM(3, 717) = 717

GCD(3, 717) = ( 3 x 717 ) / 717

= 3 / 717

= 3

Step3:

LCM(3, 576) = 576

GCD(3, 576) = ( 3 x 576 ) / 576

= 3 / 576

= 3

So, Greatest Common Divisor of 639, 618, 717, 576 is 3
