Given numbers are 475, 420, 556, 349

The list of prime factors of all numbers are

Prime factors of 475 are 5 x 5 x 19

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

Prime factors of 556 are 2 x 2 x 139

Prime factors of 349 are 349

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

Given numbers are 475, 420, 556, 349

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

Apply this formula for all numbers.

Step1:

LCM(475, 420) = 39900

GCD(475, 420) = ( 475 x 420 ) / 39900

= 475 / 420

= 475

Step2:

LCM(5, 556) = 2780

GCD(5, 556) = ( 5 x 556 ) / 2780

= 5 / 556

= 5

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 475, 420, 556, 349 is 1
