The list of prime factors of all numbers are

Prime factors of 409 are 409

Prime factors of 930 are 2 x 3 x 5 x 31

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

Prime factors of 484 are 2 x 2 x 11 x 11

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

Given numbers are 409, 930, 420, 484

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

Apply this formula for all numbers.

Step1:

LCM(409, 930) = 380370

GCD(409, 930) = ( 409 x 930 ) / 380370

= 409 / 930

= 409

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

So, Greatest Common Divisor of 409, 930, 420, 484 is 1
