Given numbers are 399, 129, 810, 134

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 129 are 3 x 43

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 134 are 2 x 67

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

Given numbers are 399, 129, 810, 134

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

Apply this formula for all numbers.

Step1:

LCM(399, 129) = 17157

GCD(399, 129) = ( 399 x 129 ) / 17157

= 399 / 129

= 399

Step2:

LCM(3, 810) = 810

GCD(3, 810) = ( 3 x 810 ) / 810

= 3 / 810

= 3

Step3:

LCM(3, 134) = 402

GCD(3, 134) = ( 3 x 134 ) / 402

= 3 / 134

= 3

So, Greatest Common Divisor of 399, 129, 810, 134 is 1
