Given numbers are 638, 395, 214, 281

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

Apply this formula for all numbers.

Step1:

LCM(638, 395) = 252010

GCD(638, 395) = ( 638 x 395 ) / 252010

= 638 / 395

= 638

Step2:

LCM(1, 214) = 214

GCD(1, 214) = ( 1 x 214 ) / 214

= 1 / 214

= 1

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 638, 395, 214, 281 is 1
