The list of prime factors of all numbers are

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 568 are 2 x 2 x 2 x 71

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

Prime factors of 393 are 3 x 131

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

Given numbers are 492, 568, 420, 393

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

Apply this formula for all numbers.

Step1:

LCM(492, 568) = 69864

GCD(492, 568) = ( 492 x 568 ) / 69864

= 492 / 568

= 492

Step2:

LCM(4, 420) = 420

GCD(4, 420) = ( 4 x 420 ) / 420

= 4 / 420

= 4

Step3:

LCM(4, 393) = 1572

GCD(4, 393) = ( 4 x 393 ) / 1572

= 4 / 393

= 4

So, Greatest Common Divisor of 492, 568, 420, 393 is 1
