Given numbers are 476, 638, 312, 809

The list of prime factors of all numbers are

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 638 are 2 x 11 x 29

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 809 are 809

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

Given numbers are 476, 638, 312, 809

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

Apply this formula for all numbers.

Step1:

LCM(476, 638) = 151844

GCD(476, 638) = ( 476 x 638 ) / 151844

= 476 / 638

= 476

Step2:

LCM(2, 312) = 312

GCD(2, 312) = ( 2 x 312 ) / 312

= 2 / 312

= 2

Step3:

LCM(2, 809) = 1618

GCD(2, 809) = ( 2 x 809 ) / 1618

= 2 / 809

= 2

So, Greatest Common Divisor of 476, 638, 312, 809 is 1
