Given numbers are 605, 426, 577, 420

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 426 are 2 x 3 x 71

Prime factors of 577 are 577

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 605, 426, 577, 420

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

Apply this formula for all numbers.

Step1:

LCM(605, 426) = 257730

GCD(605, 426) = ( 605 x 426 ) / 257730

= 605 / 426

= 605

Step2:

LCM(1, 577) = 577

GCD(1, 577) = ( 1 x 577 ) / 577

= 1 / 577

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 605, 426, 577, 420 is 1
