The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 491 are 491

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 146 are 2 x 73

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

Given numbers are 813, 491, 308, 146

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

Apply this formula for all numbers.

Step1:

LCM(813, 491) = 399183

GCD(813, 491) = ( 813 x 491 ) / 399183

= 813 / 491

= 813

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

So, Greatest Common Divisor of 813, 491, 308, 146 is 1
