The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 657 are 3 x 3 x 73

Prime factors of 748 are 2 x 2 x 11 x 17

Prime factors of 731 are 17 x 43

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

Given numbers are 813, 657, 748, 731

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

Apply this formula for all numbers.

Step1:

LCM(813, 657) = 178047

GCD(813, 657) = ( 813 x 657 ) / 178047

= 813 / 657

= 813

Step2:

LCM(3, 748) = 2244

GCD(3, 748) = ( 3 x 748 ) / 2244

= 3 / 748

= 3

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 813, 657, 748, 731 is 1
