Given numbers are 563, 565, 420, 478

The list of prime factors of all numbers are

Prime factors of 563 are 563

Prime factors of 565 are 5 x 113

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

Prime factors of 478 are 2 x 239

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

Given numbers are 563, 565, 420, 478

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

Apply this formula for all numbers.

Step1:

LCM(563, 565) = 318095

GCD(563, 565) = ( 563 x 565 ) / 318095

= 563 / 565

= 563

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 563, 565, 420, 478 is 1
