Given numbers are 645, 323, 395, 576

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 323 are 17 x 19

Prime factors of 395 are 5 x 79

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 645, 323, 395, 576

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

Apply this formula for all numbers.

Step1:

LCM(645, 323) = 208335

GCD(645, 323) = ( 645 x 323 ) / 208335

= 645 / 323

= 645

Step2:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

Step3:

LCM(1, 576) = 576

GCD(1, 576) = ( 1 x 576 ) / 576

= 1 / 576

= 1

So, Greatest Common Divisor of 645, 323, 395, 576 is 1
