The list of prime factors of all numbers are

Prime factors of 563 are 563

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 494 are 2 x 13 x 19

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

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

Given numbers are 563, 476, 494, 420

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

Apply this formula for all numbers.

Step1:

LCM(563, 476) = 267988

GCD(563, 476) = ( 563 x 476 ) / 267988

= 563 / 476

= 563

Step2:

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

= 1 / 494

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 563, 476, 494, 420 is 1
