Given numbers are 638, 627, 419, 384

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 627 are 3 x 11 x 19

Prime factors of 419 are 419

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 638, 627, 419, 384

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

Apply this formula for all numbers.

Step1:

LCM(638, 627) = 36366

GCD(638, 627) = ( 638 x 627 ) / 36366

= 638 / 627

= 638

Step2:

LCM(11, 419) = 4609

GCD(11, 419) = ( 11 x 419 ) / 4609

= 11 / 419

= 11

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 638, 627, 419, 384 is 1
