Given numbers are 639, 633, 323, 128

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

Apply this formula for all numbers.

Step1:

LCM(639, 633) = 134829

GCD(639, 633) = ( 639 x 633 ) / 134829

= 639 / 633

= 639

Step2:

LCM(3, 323) = 969

GCD(3, 323) = ( 3 x 323 ) / 969

= 3 / 323

= 3

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 639, 633, 323, 128 is 1
