The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 438 are 2 x 3 x 73

Prime factors of 634 are 2 x 317

Prime factors of 531 are 3 x 3 x 59

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

Given numbers are 818, 438, 634, 531

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

Apply this formula for all numbers.

Step1:

LCM(818, 438) = 179142

GCD(818, 438) = ( 818 x 438 ) / 179142

= 818 / 438

= 818

Step2:

LCM(2, 634) = 634

GCD(2, 634) = ( 2 x 634 ) / 634

= 2 / 634

= 2

Step3:

LCM(2, 531) = 1062

GCD(2, 531) = ( 2 x 531 ) / 1062

= 2 / 531

= 2

So, Greatest Common Divisor of 818, 438, 634, 531 is 1
