The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 105 are 3 x 5 x 7

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 481 are 13 x 37

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

Given numbers are 813, 105, 340, 481

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

Apply this formula for all numbers.

Step1:

LCM(813, 105) = 28455

GCD(813, 105) = ( 813 x 105 ) / 28455

= 813 / 105

= 813

Step2:

LCM(3, 340) = 1020

GCD(3, 340) = ( 3 x 340 ) / 1020

= 3 / 340

= 3

Step3:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

So, Greatest Common Divisor of 813, 105, 340, 481 is 1
