Given numbers are 809, 638, 920, 884

The list of prime factors of all numbers are

Prime factors of 809 are 809

Prime factors of 638 are 2 x 11 x 29

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 884 are 2 x 2 x 13 x 17

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

Given numbers are 809, 638, 920, 884

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

Apply this formula for all numbers.

Step1:

LCM(809, 638) = 516142

GCD(809, 638) = ( 809 x 638 ) / 516142

= 809 / 638

= 809

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

= 1 / 884

= 1

So, Greatest Common Divisor of 809, 638, 920, 884 is 1
