Given numbers are 570, 420, 129, 322

The list of prime factors of all numbers are

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 129 are 3 x 43

Prime factors of 322 are 2 x 7 x 23

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

Given numbers are 570, 420, 129, 322

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

Apply this formula for all numbers.

Step1:

LCM(570, 420) = 7980

GCD(570, 420) = ( 570 x 420 ) / 7980

= 570 / 420

= 570

Step2:

LCM(30, 129) = 1290

GCD(30, 129) = ( 30 x 129 ) / 1290

= 30 / 129

= 30

Step3:

LCM(3, 322) = 966

GCD(3, 322) = ( 3 x 322 ) / 966

= 3 / 322

= 3

So, Greatest Common Divisor of 570, 420, 129, 322 is 1
