Given numbers are 638, 454, 381, 847

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 454 are 2 x 227

Prime factors of 381 are 3 x 127

Prime factors of 847 are 7 x 11 x 11

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

Given numbers are 638, 454, 381, 847

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

Apply this formula for all numbers.

Step1:

LCM(638, 454) = 144826

GCD(638, 454) = ( 638 x 454 ) / 144826

= 638 / 454

= 638

Step2:

LCM(2, 381) = 762

GCD(2, 381) = ( 2 x 381 ) / 762

= 2 / 381

= 2

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 638, 454, 381, 847 is 1
