Given numbers are 420, 485, 578, 350

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 485 are 5 x 97

Prime factors of 578 are 2 x 17 x 17

Prime factors of 350 are 2 x 5 x 5 x 7

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

Given numbers are 420, 485, 578, 350

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

Apply this formula for all numbers.

Step1:

LCM(420, 485) = 40740

GCD(420, 485) = ( 420 x 485 ) / 40740

= 420 / 485

= 420

Step2:

LCM(5, 578) = 2890

GCD(5, 578) = ( 5 x 578 ) / 2890

= 5 / 578

= 5

Step3:

LCM(1, 350) = 350

GCD(1, 350) = ( 1 x 350 ) / 350

= 1 / 350

= 1

So, Greatest Common Divisor of 420, 485, 578, 350 is 1
