Given numbers are 813, 820, 199, 323

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 199 are 199

Prime factors of 323 are 17 x 19

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

Given numbers are 813, 820, 199, 323

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

Apply this formula for all numbers.

Step1:

LCM(813, 820) = 666660

GCD(813, 820) = ( 813 x 820 ) / 666660

= 813 / 820

= 813

Step2:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

Step3:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1

So, Greatest Common Divisor of 813, 820, 199, 323 is 1
