Given numbers are 813, 166, 341, 420

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 166 are 2 x 83

Prime factors of 341 are 11 x 31

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 813, 166, 341, 420

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

Apply this formula for all numbers.

Step1:

LCM(813, 166) = 134958

GCD(813, 166) = ( 813 x 166 ) / 134958

= 813 / 166

= 813

Step2:

LCM(1, 341) = 341

GCD(1, 341) = ( 1 x 341 ) / 341

= 1 / 341

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 813, 166, 341, 420 is 1
