Given numbers are 639, 180, 975, 453

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

Apply this formula for all numbers.

Step1:

LCM(639, 180) = 12780

GCD(639, 180) = ( 639 x 180 ) / 12780

= 639 / 180

= 639

Step2:

LCM(9, 975) = 2925

GCD(9, 975) = ( 9 x 975 ) / 2925

= 9 / 975

= 9

Step3:

LCM(3, 453) = 453

GCD(3, 453) = ( 3 x 453 ) / 453

= 3 / 453

= 3

So, Greatest Common Divisor of 639, 180, 975, 453 is 3
