Given numbers are 639, 390, 599, 423

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

Apply this formula for all numbers.

Step1:

LCM(639, 390) = 83070

GCD(639, 390) = ( 639 x 390 ) / 83070

= 639 / 390

= 639

Step2:

LCM(3, 599) = 1797

GCD(3, 599) = ( 3 x 599 ) / 1797

= 3 / 599

= 3

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 639, 390, 599, 423 is 1
