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

Apply this formula for all numbers.

Step1:

LCM(639, 128) = 81792

GCD(639, 128) = ( 639 x 128 ) / 81792

= 639 / 128

= 639

Step2:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 639, 128, 631 is 1
