Given numbers are 420, 609, 889, 577

The list of prime factors of all numbers are

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

Prime factors of 609 are 3 x 7 x 29

Prime factors of 889 are 7 x 127

Prime factors of 577 are 577

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

Given numbers are 420, 609, 889, 577

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

Apply this formula for all numbers.

Step1:

LCM(420, 609) = 12180

GCD(420, 609) = ( 420 x 609 ) / 12180

= 420 / 609

= 420

Step2:

LCM(21, 889) = 2667

GCD(21, 889) = ( 21 x 889 ) / 2667

= 21 / 889

= 21

Step3:

LCM(7, 577) = 4039

GCD(7, 577) = ( 7 x 577 ) / 4039

= 7 / 577

= 7

So, Greatest Common Divisor of 420, 609, 889, 577 is 1
