Given numbers are 397, 519, 485, 420

The list of prime factors of all numbers are

Prime factors of 397 are 397

Prime factors of 519 are 3 x 173

Prime factors of 485 are 5 x 97

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 397, 519, 485, 420

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

Apply this formula for all numbers.

Step1:

LCM(397, 519) = 206043

GCD(397, 519) = ( 397 x 519 ) / 206043

= 397 / 519

= 397

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 397, 519, 485, 420 is 1
