Given numbers are 639, 429, 381, 449

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

Apply this formula for all numbers.

Step1:

LCM(639, 429) = 91377

GCD(639, 429) = ( 639 x 429 ) / 91377

= 639 / 429

= 639

Step2:

LCM(3, 381) = 381

GCD(3, 381) = ( 3 x 381 ) / 381

= 3 / 381

= 3

Step3:

LCM(3, 449) = 1347

GCD(3, 449) = ( 3 x 449 ) / 1347

= 3 / 449

= 3

So, Greatest Common Divisor of 639, 429, 381, 449 is 1
