Given numbers are 638, 565, 347, 404

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 565 are 5 x 113

Prime factors of 347 are 347

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 638, 565, 347, 404

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

Apply this formula for all numbers.

Step1:

LCM(638, 565) = 360470

GCD(638, 565) = ( 638 x 565 ) / 360470

= 638 / 565

= 638

Step2:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 638, 565, 347, 404 is 1
