Given numbers are 813, 522, 321, 172

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 321 are 3 x 107

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 813, 522, 321, 172

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

Apply this formula for all numbers.

Step1:

LCM(813, 522) = 141462

GCD(813, 522) = ( 813 x 522 ) / 141462

= 813 / 522

= 813

Step2:

LCM(3, 321) = 321

GCD(3, 321) = ( 3 x 321 ) / 321

= 3 / 321

= 3

Step3:

LCM(3, 172) = 516

GCD(3, 172) = ( 3 x 172 ) / 516

= 3 / 172

= 3

So, Greatest Common Divisor of 813, 522, 321, 172 is 1
