Given numbers are 813, 312, 173, 558

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 173 are 173

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 813, 312, 173, 558

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

Apply this formula for all numbers.

Step1:

LCM(813, 312) = 84552

GCD(813, 312) = ( 813 x 312 ) / 84552

= 813 / 312

= 813

Step2:

LCM(3, 173) = 519

GCD(3, 173) = ( 3 x 173 ) / 519

= 3 / 173

= 3

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 813, 312, 173, 558 is 1
